Are you talking specifically about the new Kirby game or just abilities that haven't appeared in a long time that should make a comeback?
Abilities that haven't been in a game for while that can make a comeback in the new game or a future game.
Animal and ufo
Ufo was really fun to play around with & with the new 3D environment, it could come back.
Ummmmmmmm any true fan would say this:
ALL OF THEM!!!!! (Including the ones that he gets from inhaling fighters in smash bros.)
I think animal, i havent played squeak squad though so idk ;;
What do you think?
