The stage is on a 2 minute timer, that is to say it takes a full 2 minutes exactly for it to reach back to it's original position. All the platforms at the B position are constant, they never disappear. Only the things at C disappear/appear which are the pendlum, the two platforms above the pendulum, the tilting platform, the two platforms next to the 3 doughnut blocks, and the wall and all surrounding platforms by the wall. The carpets also disappear, but they reappear at about 2-3 seconds after they disappear at their original location. The platforms that are semi permeable are close to the same as the ones that disappear. The two platforms next to the 3 doughnut blocks at part B are semi permeable, the two platforms that appear above the pendulum are semi permeable, the platform to the left of the wall is semipermable, all of the carpets are semipermeable, and the main floor on part D is semipermeable. During the boat phase it moves up and then it rapidly goes down during the end of it.
When the time is at :48 of an odd minute (assuming it's 8 minute) then the mast of the boat is directly below the 3 doughnut blocks at the top that you can actually touch meaning if someone like snake utilted at the mast and you DIed directly up at :48 then you will hit the doughnut blocks instead of dieing and can get hit back, It takes about 3 seconds to move from the middle of the boat to either end so at :51 and :45 the edges of the boat will be directly below the blocks. At about :33-37 the pendulum doughnut blocks are also within the blastzone and you can hit those. When you can see the first half of the rainbow from the boat then you can reach part B of the stage (as in grabbing the edge), since the boat moves up and then down the edge is like right in the corner of the blastzone so if you ever go for it and you just keep falling at the left side you will grab the edge, don't be shocked if you don't grab it sooner. Shortly after the boat hits the stage then the ceilings will start to rise a lot from below. At :17 (still with the odd integet with 8 minute time limit) the two platforms appear by the doughnut blocks. At :12 the tilting platform spawns. At :07 the top left platform spawns. The pendulum spawns when the right platform to the 3 doughnut blocks disappears. The top right platform spawns when the top left platform disappears. When the pendulum swings to the right after all of this the platform to the left wall spawns and the rest appears within a couple of seconds later. The 3 doughnut blocks on the top are constant so they are reachable during when any of these things are being transitioned to (even if it's offscreen it can still be in the blastzone and be used as a recovery option).
The top 3 doughnut blocks that connect to the curve thing have some strange properties where if you grab them where they intersect and do a certain throw they might appear get stage spiked by the block and appear below you:

The semi circle curvy surface there sometimes also gltiches and players can fall through like on PS1 and delfino.

When the left top wall disappears, the bottom wall and the platform underneath is reachable (characters with glide can glide to it etc).
During this whole top place the ceilings are lower. When the stage transitions back to the boat everything is shifting down so you will fall faster during this part and when you jump or get hit up you will barely go anywhere. Also you can't kill yourself by going up on the ceiling in any stage unless you get hit (or you're wario with a waft). This can be manipulated when the stage shifts down by using a recovery move or holding down while using a midair jump and you won't die. Any character can do this, but you must account for the stage shifting you down drastically so like MK's up-b you'll be shortly back onto the ground after using it. You can see this being abused here:

This can be used if you get trapped up on top and need to get back down, but you can't land on the ground or you'll die. Technically characters ISJR forever up there if done right, but the platforms make it hard since you can't see them and if you land on them you'll die.
There are 6 edges on the stage, 2 on the boat, 2 at the B spot where the boat crashes, one at the doughnut block at the top semi circle, and 1 at the doughnut block at the top wall. If you grab the edge and then stand on then someone stands on the doughnut block and makes it fall while you are hanging on the edge then you will get pushed down while you are in the "hanging on the edge" state, you do a get up option during any of this you will be teleported back to the edge
The magic carpets are 'wavy' and can be counted as a very small slope so you might air release waario here or throw snake's grenade down and they get launched at an angle. The top bottom of the doughnut blocks on the sides can also be counted as an angled side.
When the boat crashes and you grab onto the ledge while it falls some get options are unsafe because they'll just put you below the edge, the best thing to do most of the time is to just drop back and midair jump back.
Many characters can midair jump off the right side edge or land with an aerial and get a wavedash like effect.
There is a wall underneath the fan on the right of the boat that people can wall cling too.
Some characters have different air release options depending on if it's going up/down/left/right. For example, Marth can tipper fsmash MK when he grabs him from the top part since it's going right when he faces left.
That's all of the basic general stuff that I can think of atm, so character specific stuff:
Bowser: Not much he can do, he can down-b on the left boat edge as it hits the stage and you will cancel directly into your standing animation since you'll be big enough to be on the stage after you grab the edge. If you down-b on the top 2 edges since the stage is moving you'll cancel directly into your standing animation as well.
Captain Falcon: **** turning, too good. He can falcon kick edge cancel on the boat from the mast. Can falcon kick under B when the boat goes down and recover on the other side. Can also ride the top 3 doughnut blocks down and falcon kick and up-b to the bottom platform
Diddy Kong: Banana locks against walls, up-b into stuff is awesome too:
http://www.youtube.com/watch?v=v4Z8ShCgIms&list=UUy-8wdwVQ21fspfy2bosOAA&feature=plcp
DK:He has a lot of up-b tricks. He can get his invincibility up-b on the left side of the boat and land on the mast on the platforms. He can do his general up-b stuff off of platforms and right side of the boat. All of the platforms also helps with up-b shenanigans and stuff. Cargo down throw to dtilt on wall is a true combo
Falco: He can control air space well with his lasers and stuff. 0 to death on boat part:
http://www.youtube.com/watch?v=8_qrN11lcUQ
^^^^ftilt is also really good on the boat since it sets up for a laser lock well without a wall so it sets it up even better with one. His reflector goes through walls and stuff
Fox: He can use rising fair and shine stall to get around the map well. He can go under the top part by riding a doughnut block down and then shine stalling since the map moves you'll go to the right, then use riding fair after you fall too low and then up-b into the wall and hold to the right and you'll land on the bottom platform. Can shine wall infinite.
He can use the slope (like the small slope on the boat) to flamedash into (up-b into the slope and you'll bounce off of it and land on the slope, cancels your lag really well on slopes).
GaW: Can use his nair, uair, and up-b to get around and control air space well. Not many "tricks" that he can do per se, he can uair kill well here and stuff. His dtilt locks on the wall well and he can use his dtilt to his people off the left side boat edge through the stage. I believe if GaW does a jump from the right ledge he will just appear on stage.
Ganon: **** turning still too good. Pretty much everything falcon can do with falcon kick also.
Ice Climbers: Has wall infinites and stuff, has some ice block tricks with slopes and stuff.
Ike: Can wall infinite on certain walls, but not the boat wall, it's too small, but can still be used to combo.
Jigglypuff: Can midair jump off the right side of the boat and get a wavedash like effect.
D3: Can infinite a lot of characters off the wall. On the boat he can't CG some characters off the small slope on the left boat part like Diddy, but he can also use the slope to infinite a few characters like Wario. D3 can also standing infinite a few more characters at the top part while it scrolls to the right when he faces the left like wario, captain falcon, link, ivysaur.
Kirby: He can do the stone glitch like on PS1 and picto on the right edge of the boat, but it must be spaces. He can also uthrow kill on the right side and stuff and he can uthrow SD on the pendulum
Link: Not much, he has a decent jab lock setup on the wall and gale guarding is decent.
Lucario: Not much, he can use his up-b to cling to some walls and he has a really high wall jump
Lucas: He can use his zap jumping and stuff to get around the stage decently well.
Luigi:....like nothing...?
Mario: Decent *** lock set up with ftilt and jab on the wall
Marth: good dtilt on walls. When the boat lands and it's going down it's above the stage for a short amount of time. Dthrow to buffer turn around dtilt on wall is a true combo
MK: Can up-b cancel easily, if people are planking you on left side boat and try to hit you through it you can invin ground up-b them from on stage. MK can drill rush through the slope at part B from underneath it and appear through it. Uthrow kills and SDs and stuff.
Ness: not much, he can get the appear below stage throw thing at the top easier than most characters I find
Olimar: up-b through walls and stuff.
Peach: Can get the wavedash effect easily on right side of the boat. She can float and the stage will move and she'll go up if you need to stall for a bit.
Pikachu: Can dthrow CG on carpets longer since it goes up, thunder also works well on this stage.
Pit: Nothing much
PT: Zero switch anywhere pretty much. Squirtle can use the slopes and if he does a rising aerial on it he'll get a wavedash like effect up the slope. Ivysaur can up-b on some parts and land on the ground for some mindgames.
ROB: Has some gyro tricks against the wall and stuff
Samus: Zair goes through walls
Sheik: Nothing much, some up-b momentum boost off edges help in some places.
Snake: Grenades bounce a lot so that can help when on the boat against the wall or against any slopes. His up-b has a lot of vertical movement which helps in the 2nd part, his utilt really helps on the pendulum part.
Sonic: Can get spindash invincibility in a lot of places. If he up-bs below a doughnut block on a carpet he'll be stuck getting bounced for a bit.
Toon Link: Can use his dair to slide on some slopes to make it harder to punish, his run away game is really good on this game with bombs also.
Wario: As shown before you can use side-b to ride the top part without dieing. Can get air released on a lot of the slopes like the small slope on the boat and stuff.
Wolf: He an air release some characters to side-b for a spike and still live sometimes depending on where RC is
Yoshi: Can use his down-b on some slopes near edges of stages and he'll slide off the stage with no lag so he can instantly go into anything.
Zelda: She has some spots where she can up-b cancel easily. She can up-b from the bottom mast to the left edge, edge cancel with up-b on top mast to the right side. Halfway up the slope at part B she can cancel onto left side. She can cancel on the pendulum when it's completely tilted one way by standing on one of the circle and going to the other side and another by standing on the doughnut block on the far right and cancel to the right most platform at the top.
Zero Suit: Her up-b goes through some stuff, her side-b too. Her armor pieces bounce a lot so she can use it with slopes and the wall on RC.
This was just all off the top of my head, probably forgetting stuff, i'll add more later if I can think of stuff.
