"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 guessess what it is. Using a felt-tip pen, Grampu draws a bunny rabbit while giving the viewer clues as to what it is. When the drawing is finished, Oobi guesses that it's a rabbit and wins the game. They celebrate by clapping their hands together.
