I had written a presentation of this series for children, but it disappeared, so here is a new post.

Infos
A spanish series for Zinkia Entertainment, quickly bought by the british and translated (well, at least the narrator and the children voices) for broadcast on cITV
Created by: David Cantolla, Luis Gallego, Guillermo García Carsi
Written by: Guillermo García Carsí, Andy Yerkes, Ken Scarborough

Cast
Narrator: Stephen Fry
Pocoyo: Alex Kearns

Summary
Pocoyo is a 4 years old kid, all clothed in blue, and accompagnied by his friends Pato the duck, Elly the elephant, Sleepy Bird, and Loula the dog. Some visitors, like the Ball Orchestra, Octopus (Fred), or Butterfly. He lives many amusing adventures, narrated by Stephen Fry, with much joy and humour, from the building of a block tower to dance or to the problems of sneezing.

My advice
Honestly, a great series, recommended to all, children and grown ups. Fun situations, a very clean narration in a perfect British English, no stupid assumption that your kid will answer correctly, light and cute “drawing”, this is one of my favourite picks for children (so, for Matt’, naturally). I would suggest buying the DVDs if you can afford them, 13 episodes on each is already a lot.
