Mama & Tuxie
Character overview: Mama and Tuxie are two halves of a character in the most literal sense. Tuxie wanders around aimlessly onstage, having a mind of its own, being able to take damage and knockback, and he is the easiest character in the cast to launch. He will use a double jump and a small penguin flutter if launched offstage, but not KO'd, though this recovery isn't very good. He'll run in distress when an attack near him misses, but other than that he is oblivious to the action entirely. The other half of the character is Mama, who is large and heavy, does large startup attacks with heavy armor, deals high damage and knockback in her attacks, and has great mobility thanks to her Side B (more on that later). KO'ing Mama does not result in the mother-son duo losing a stock, but it does result in the Mama player now gaining control of Tuxie who has very limited options. Tuxie's not very fast as he has yet to learn how to slide like his Mama. KO'ing Tuxie, whether or not Mama has been KO'd, will result in the loss of a stock for the Mama & Tuxie player, and Mama will disappear momentarily for the duo to respawn if it is not their last stock. As the Mama player, you have to keep Tuxie safe with your strong attacks, and if you've transitioned to playing as Tuxie, you now have to either run out the clock or get little spurts of damage in while you can.
Below are Mama's specials.
Side B: Belly Slide
Mama takes a few steps forward before sliding on her belly. This move has a bit of startup and acts like a heavy dash attack in NASB, gives you a lot of speed and the momentum can be carried over if you cancel the attack after hitting someone.
Neutral B: Icy Slap
Basically the old Ice Climbers neutral b, however it now has a weak hitbox when Mama slaps the pair of small iceberg projectiles.
Down B: Peck
A three-level chargeable forward peck, with super armor if you charge past the first level. Level One is a medium-range poking tool that can set up a techchase situation (which you can follow up on with Side B), second level is a bit stronger and can freeze at the sweetspot, and the third level kills and destroys full shields. It is impossible to store the charge over the time, but you can cancel the attack by shielding, jumping, or rolling.
Up B: Snowy Swap
This is a bit of a weird one. In Chess, you can sometimes swap the places of your Rook and your King, called Castling, and this duo has the same deal for their Up B. Both characters are momentarily covered in an icy, dusty cloud, during which they are invulnerable and impossible to see. When the move ends, Mama is where Tuxie was and vice versa. Each one has a very strong hitbox on the attack when they spawn. Imagine Orcane's Up B if the puddle was a completely separate character. You can use this to quickly get Tuxie out of trouble or if you've run out of your double jump with Mama offstage and think Tuxie might be able to make it back safely. You don't regain control immediatly though, as both penguins will be somewhat dizzy after the swap, so do be extremely careful when using this high-risk, high-reward attack.
And here are Tuxie's two attacks:
Neutral Attack: Tiny Icy Slap
Only spawns one iceberg like Sopo and doesn't have as large of a hitbox as Mama's.
Special Attack: Flutter Jump
Has heavy armor like Yoshi's, but doesn't go nearly as far or as high. Does small amount of damage and is a quick get off me tool.\
Tuxie can do anything the other characters can movement wise.
