Boi

In an underwater setting, SpongeBob SquarePants receives a pink, spiky object from Patrick Star, then uses a glowing blue device to transform it into a large, monstrous version of himself, which he then holds with a wide, toothy grin. Squidward Tentacles appears in shock as SpongeBob's transformed form, now with a large, fleshy head and a brown tie, runs forward with a determined expression.
