"Izzy", Mascot of the 1996 Atlanta Olympic Games

Details: The mascot of the 1996 Summer Olympic Games in Atlanta was an amorphous abstract fantasy figure. It carried the name "Izzy", derived from "Whatizit?" because no one seemed to know exactly what "Izzy" really was.

He changed his appearance several times after the closing ceremony in Barcelona in 1992. Over time he grew a mouth where only lips had existed, he added stars in his eyes, bulked up and gained muscles in his previously spindly legs, and eventually sprouted a nose.
