You're probably asking yourself, "Who is Pocoyo? and Why do I want him in my bath?!
Pocoyo, which means 'Little Me' in Spanish, is a TV series that follows the adventures of a 3-year-old Pocoyo and his sidekicks Elly (an Elephant), Pato (a duck) and Loula (a dog.) As one might expect, Pocoyo does all kind of silly stuff and dances around quite a lot, talking to both himself and to the narrator (the English version is narrated by Stephen Fry.)
Pocoyo became so popular worldwide that he expanded into a whole online virtual extravaganza chock full of games, webisodes and more which was given a 4 star review by Common Sense Media. No wonder the little guy has such a big head!
