Inviso

Inviso is a boss from Yoshi's Story. He is at the end of Stage 3-2: Tall Tower. Invisoâ€™s appearance is somewhat hidden, as he is invisible (minus the fact that the world reflects on him). Inviso attacks by turning invisible and trying to bump into Yoshi while summoning Peep-Cheeps. Yoshi can defeat Inviso by hitting him with three eggs.

Inviso seems obsessed with the game of Peek-a-Boo.
