Pocoyo (2005-2009) is a Spanish children's Animated Series, narrated by José María del Río. (Stephen Fry or Adal Ramones, depending on the version you watch). Tells the adventures of a young boy named Pocoyo, the duck Pato, the elephant Elly, and more. Notable for its minimalist style- the characters lack any textures and all of the action takes place on a white background, and there is no backstory.Also notable for being absolutely, unbearably adorable.
Nice Guy: The narrator. He's always ready to intervene in all conflicts than arise, he is usually the one that administers the moral of the day, and the characters seem to like him quite a lot - for a disembodied voice he sure has a lot of personality.
No Fourth Wall: The narrator, Stephen Fry, José María del Río, or Adal Ramones, depending on the version (English, Castilian Spanish, and Latin American Spanish, respectively) asks the viewer to various things from pepping up Pocoyo when he's feeling sad, to waking up Sleepy Bird.
Not Allowed to Grow Up: Pocoyo's birthday is on October 14th, but when his "birthday" rolls around, he's still four!
Parental Bonus: Pocoyo is surprisingly watchable by parents - and the creators probably know, as there are lots of small easter eggs that won't be noticed by kids. For example, in the episode "Boo", when Pocoyo scares Pato in the shower, it's very reminiscent of the famous shower scene in "Psycho". And, in the episode "Dance off!" Pato and Pocoyo hold a dance competition - and at one point Pocoyo starts playing air-guitar. The song that plays is very reminiscent of Metallica, and Pocoyo has Octopus on his head, looking a bit like Kirk Hammett.
