Fizzlit

Fizzlits are small purple blob-like enemies that first appear in Super Mario Galaxy 2. Their body is purple with eyes that have a yellow pupil and a black iris. In Super Mario Galaxy 2 their bottom is tooth-shaped while in Super Mario 3D World their bottom resembles a suction cup. They turn into a yellow electric puddle that is either a square or a circle when attacking.

Super Mario Galaxy 2
Fizzlits first appear in Super Mario Galaxy 2 where they mainly attack by hopping from one place to another and spreading into a round electric puddle, which will shock and damage the player upon contact. Fizzlits are only vulnerable when they are in their non-electric state, during which the player can use any form of attack to defeat them. They can also be defeated by eating them with Yoshi. However, the enemies are still harmful when simply touched from the sides. Fizzlits mostly inhabit industrial levels, such as in Bowser Jr.'s Fearsome Fleet, and in Bowser Jr.'s Boom Bunker, but are also encountered in Cosmic Cove Galaxy.

Super Mario 3D World
Fizzlits reappear in Super Mario 3D World, being now roughly square-shaped with connected eyes. They retain the same method of attack from before: generating an electric puddle in an attempt to damage the playable characters. However, Fizzlits cannot jump around and are stuck to the ground permanently. The puddle they melt into is now square, and their entire faces can be seen on top of the puddle, rather than their eyes poking out as they did in their previous appearance. The puddles are now smaller as well. When in their puddle state, they can move from side to side in fixed paths before reverting to their solid forms. When they spread, Fizzlits look in the direction they move.
