For whatever reason… I never saw this >_<. Sorry dude!
Anyway, Diddy big disadvantage. Hydranting up airs is good and all, but you can only drop one and if Diddy can grab you again while one is down, you are gonna be in pain. Not to mention the Diddy I faced who utterly destroyed me on FG barely used Up Air anyway, he just followed my DI and used Bairs or Fairs. Grab is usually used while tripped up and if Diddy is doing that like he should, then you cant just trampoline out of a grab. Fruit destroys bananas? How? I would love to know, maybe its just a disadvantage but I dont see Pac beats Diddy in any way. Diddy has so many tools and options that getting him off stage to gimp him isnt always easy.
Fruit is useless against Yoshi. Eggs are way too powerful a tool and arent exactly easy to powershield. They really, really interrupt Pac Mans ability to charge fruit if used correctly. It basically becomes a game where the only time to charge fruit is when Yoshi is off stage and as soon he is back on, egg pressure and rushdown pressure is real. You cannot also afford to make any mistakes against Yoshi because he can kill you so much earlier than you can kill him. Dair is a real problem because of this as it does a ridiculous amount of damage because of this. I have to ask, whats your experience with Yoshi? Because I have played some on FG and one IRL and I have to say, FG Yoshis are generally bad and dont use eggs properly at all. FG Yoshis had me thinking that Yoshi was going to be easy for us. I was wrong. Oh and Orange gimping (one of our earliest killing tools) is essentially useless because of jump armour. I just cant see how in anyway Yoshi is beatable by us. His pressure game is amazing and lives and hits harder than us by a large amount.
Alright. Well I have a lot to say, so please forgive me in advance for my wall of text lol.
I'll let you listen to some awesome pacman world 2 music while you read.
So kick back and relax, it's gonna be a while XD.
To start off, how is diddy approaching us easily? Set up a trampoline & hydrant wall in the middle of the stage and start charging your fruit to either the melong or galaxian. These are the fruits that completely ruin diddy' day. After he manages to jump over your fort (possibly using his double jump in the process or using monkey flip, punish his landing with either up smash or utilt. Diddy hates being directly above his opponent, and that's where we can manage to keep him all the time, while messing up his ground game with hydrant and trampoline stage control. The trampoline protects the hydrant from being launched by diddy, and makes a wall that diddy is forced to jump over and approach, or wait and let us charge all day, just for us to set it up again. While there is no hydrant or trampoline on the field (even though there should always be in this matchup) you must have your melon or galaxian if you are going in for an approach, or use your cherry, strawberry, and orange if diddy charges at you. If diddy throws a banana, you can throw any fruit to destroy it (cherry and strawberry are the fastest for this) due to the horrible priority of the banana peel. You can then predict his grab (which is easy against this grab reliant character) and punish. This is a battle that utilizes Pac-Man's versatility the greatest. You charge in with a melon or galaxian to force him to shield, because he can jump over the melon without getting punished by a fair, RAR bair, or nair if you're close enough. The galaxian forces him to sheild which gives you a free grab into forward throw which should throw him back into the galaxian for more damage, and confirms another hit for you to follow up with.
You need to remember this pattern, throw weaker fruit and set up your fortress to ruin approaches, and use your firtress to buy time to get you the fruit you need to charge in. Getting him above you is a huge advantage for you, so use the trampoline to punish any attacks that land on your sheild, and always punish him when he jump on your trampoline. The Apple is key for this, as it always forces him into the air. Doing all of this will push him further towards the ledge, which is where you destroy him with a gimp of your choice depending on where he recovers from. The Orange, melon, and key are for horizontal approaches, and the Apple, hydrant, and bell are for vertical recoveries. Aerials can punish him from horizontal or vertical depending on how safe you feel timing your aerial to challenge his monkey flip. The Bell is for stealing extremely early kills if you get the opportunity to charge it (remember to build your fortress when you need high tier fruit)
Switch between playing safe and aggressive and you should be able to destroy diddy.
Now for yoshi. I fight on smash ladder, which is where I fight many great players, including diddys and yoshis.
I fought the most annoying yoshi in my entire life. He kept pressuring me with eggs the entire match, and racked up so much damage. But what I noticed, is that he couldn't really follow up his egg spam when he threw them while he was in the air. He just couldn't land quick enough to punish. And if he used eggs on the ground, I would build a fortress to stay away from the eggs and waited for him to come to me. This is a match of great patience. Use the trampoline and hydrant to gain space, and that's how you charge your fruit. Yoshi is normally really good at approaching from above due to his crazy dair and down B, but we have an amazing tool in our usmash to counteract these threats. When yoshi jumps over your fort, he can only approach with fair, dair, down B, or nair. All are punished my Usmash or utilt. The reason why I always say use utilt to stop landings is because of a special aspect of it that was discovered; we have invincibility throughout most of the attack, similar to G&W's usmash. Usmash is better for punishing down B landings due to how long the hitbox lasts for, and is better for punish yoshis fair because we have more priority. Utilit is great for punishing nair and dair approaches thought because of its better horizontal reach (I suggest using this move backwards though, because it has more reach in the back)
You always want yoshi to approach you in this matchup, so setting up your fort is a great way to lure yoshi in, because they want to stop you from charging. Whenever a yoshi is above you while throwing eggs, run up and up air. Yoshi's blind spot is diagonally below him, so approach him from there with your uair and fair. This should make it much easier to beat his egg spam. Also, I'm not sure yet, but I think our invincible utilt can cancel out his eggs. I should probably test this first. But I know that you can use your side B, to aim at the eggs, and cancel them out, giving you 2% per pellet. This removes his best pressure option. You definitely want to be on the defensive in this matchup most of the time. When you do go in, use your galaxian to destroy incoming eggs with its wide loop, and punish yoshi's cool down after throwing the eggs. Never go on without a fruit, and use cherries and strawberries in mid range to stop short hop approaches.
Just be patient, and punish yoshi's mistakes. You can kill yoshi with the bell easier than most characters because of how much yoshi loves to short hop egg approach. The bell outprioritizes the egg, and nails yoshi, giving you a free usmash. Up smashes, throwing hydrants, and gimping with the melon instead of orange (because it beats yoshi's super armor, and moves slowly, forcing yoshi to maneuver around it, giving us more time to fair or nair gimp. If you want another option for kills, you can try to use the side B as a mixup to punish rolls and attack yoshi's in the air while they throw eggs (situational, but possible)
Remember to throw your hydrant at the opponent only sparingly ( or as a defensive tool to protect you from eggs by using the bair ->jab technique)
And NEVER be above yoshi. You don't want to eat an usmash or an uair. If you do end up in the air, only use the hydrant when the yoshi goes for an uair. Don't uae it if they stay on the ground, because they can send it back with an usmash. Instead, use the apple to snipe yoshi on the ground, and get him into the air as you land, so you can turn the tides on him.
Be creative with your limitless tools and be patient. Then you should be able to easily handle both of these characters in the long run.
Edit: just something everyone should know, villager vs pacman games are so fun. It's a battle of mind games. We can fake out the pocket by throwing a hydrant immediately followed by a key, and we destroy villager up close. Don't be too far away though, he'll pester you with fairs and dairs. Although the fruits can out prioritize villager's fair and dair. Keep a cherry and strawberry in hand to use as a sheild.
? Mostly FG experience, but I find her the most troublesome character to go against.
