Lenny Penguin is the main character of the 1993 computer game Lenny's Music Toons. He is an anthropomorphic penguin who lives in an apartment. Nobody lives with him but a fish, a parrot, and a living teddy bear. He did have relatives, but their current status is unknown.
His known heroic role was in the "Puzzle Books" part of the game. First of all, a gorilla in overalls plans on capturing a cat, punching part of the background into a puzzle. When the cat takes a puzzle piece, the player must put it into the right place. The more mistakes the player makes, the closer the gorilla gets to climbing up the tree on the left, and if he is close enough, he captures the cat and puts him in a cage in the manhole. However, whenever the player puts a piece in its correct place, it gets Lenny closer to saving the cat. Once it is all reassembled, Lenny fetches the cat and jumps down with an umbrella for a parachute, and the cat goes into the hole of the tree on the right. Clicking on that hole shows how many cats Lenny saves.
