Kevin the cucumber is so cool - everybody knows it! Whenever anyone gets hot and bothered, cucumber is always there to cool them down. He even has his own, cool cucumber song: "I'm super cool Kevin and this is my song! Make like a cucumber, you can't go wrong. You wanna be cool? Then repeat after me: I am a cucumber, cool as can be!" But when Kevin starts to feel left out, something happens that has never happened before: Kevin. Loses. His. Cool! Will Kevin's friends be there for him when he needs them most?
