Wouldn't it be great if we saw gooey in smash as a fighter?

Yes.
Moveset??

Neutral special would be the same thing as Kirby's neutral but with a tongue.
The side special would be a broom.
The up special would be mimic matter.
Down special would be Rock.
Final smash would be all of Kirby's friends beating up the fighters that were caught in gooey's tongue.

I officially need this for DLC

um no
