Shh...Cookie and Broccoli's lips are sealed! That is, until the whole school happens upon Broccoli's hiding spot and overhears his super-secret nickname--and are much more encouraging than he expected. Then, Talking Rock gives the duo a cryptic clue to solving Broccoli's boredom--the solution is the opposite of boredom. Well, the opposite of boredom is the Funnest Thing Ever, right? Cookie and Broccoli try a silly screaming contest, a bubble-blowing party, and a real-life food pyramid, but the true Funnest Thing Ever might have been in front of them all along. And it's even more enjoyable when it's not a secret anymore!
