Big has written his first play and the cast - Small, Ruby and Twiba - are waiting backstage to perform it. T-Rex and the Frogs are a patient audience. Small, however, is unhappy with the role that Big has given him because it doesn't sound much fun, so he swaps with Ruby.

However, as the play progresses Small realises that he made a mistake and that Ruby now has a much better part, so they swap back again in time for the second act. During the second act, Small realises he made another mistake and that his own character is asleep the whole time!

At the end of the play Small is very unhappy, until Big points out that there is still the final song to sing: does Small want to do this? Of course he does! Small leads the cast in the finale to the loud croaks of appreciation from the Frogs.
