So in case you aren't aware in 2005, Cartoon Network made a preschool block called Tickle U.

I suppose this was supposed to compete with Nick Jr. and Playhouse Disney. It was dedicated entirely to preschool shows most notably Peppa Pig and Krypto the Superdog. Needless to say this block failed and surprisingly not many people ever remember or talk about this block. It only ran for like a year and a half I guess because Cartoon Network was more dedicated to non-educational cartoons.
