"Drawing Game!" is one of the Oobi shorts.
Oobi and Grampu are in the playroom with an art easel. They decide to play a guessing game where Grampu draws something and Oobi guesses what it is. Using a felt-tip pen, Grampu draws a bunny rabbit while giving the viewer clues as to what it is. When he draws a circle for the head, off-screen voices guess three things: a pizza, a snowball, and the planet Earth.
Grampu gives a second clue: a pair of eyes. The voices give a few more guesses: a jellyfish, a chicken, and the man in the moon. Grampu draws a pair of whiskers, and the voices guess again: a kitten, a dog, and a lion. Grampu finishes the drawing by adding a pair of bunny ears. One of the voices jokes, "I know: it's my uncle Ned!" The other voices laugh and say it's a bunny rabbit. Oobi guesses the same thing and wins the game. He and Grampu celebrate by clapping their hands together.
