Alright, so I really enjoyed that SpongeBob breakdown!
We learned quite a bit about his playstyle and moveset (in particular, how his Bubbles come out less frequently if used in rapid succession; that's good to know), and he looks pretty fun for your typical jack-of-all-trades character!
Also, both "Floor Sweep" and "Imaginaaation Clap" can spike; that's kind of hilarious!
Also also, regarding Jellyfish Fields as "his stage", I'm gonna wait and see if they do a breakdown with Sandy as well as who they place at the Technodrome before I say anything more regarding Stage Theory. But if Sandy DOES get placed in Flying Dutchman's Ship and Leonardo in Technodrome...at that point, I would say that Stage Theory might actually be a thing.
Finally, we not only have confirmation of Victory animations, but also potentially unique losing animations as well? That's pretty cool, considering in Smash most of the characters are just seen clapping for the victor.
