Wimzie and the gang enter a jingle contest for Banana Bits Cereal, to win a rock-and-rolling wagon, and a year supply of Banana Bits. Wimzie wins the contest, but is devestated to find out she hates the cereal. Wimzie has second thoughts about performing her jingle on TV, because her jingle states how much she loves the cereal. But Wimzie still wants a rock-and-rolling wagon, and gets an idea. Once on TV, Wimzie introduces the gang, who perform the jingle for her. In the end, Horace, Jonas and Lou Lou win a wagon, and so does Wimzie.
