Pengo
Pengo is a video game. It was originally an arcade game made by Sega in 1982. Subsequently versions were made for many of the home consoles/computers.Pengo the Penguin is the eponymous star of Pengo the video game. The basic layout of Pengo is akin to Pac-Man, in that it's a top down, 2D, gridlike arrangement. The "maze" is made from blocks of ice that Pengo can push to obliterate the enemies - the "Sno-Bees".
One of Pengo's distinguishing features is its "interactive walls". If Pengo pushes the wall it goes into "freeze mode", and any Sno-Bees next to the wall are instantly frozen.
Pengo was a fun game, and it used Popcorn as its theme music.
