After going to a Halloween party, Cowbella reveals that she is nervous about trick or treating tomorrow because she didn't like all the scary vampires and zombies they saw at the party today. The Pajanimals travel to Storybook Land, where Edwin explains to Cowbella that there's nothing to be scared of. Those vampires and werewolves, etc. are just costumes that the big kids wear to have fun, just like her pretty princess costume!
