Peppa Pig is a British preschool animated television series directed and produced by Astley Baker Davies in association with Entertainment One, Nick Jr. and Channel 5. The U.S. dub aired as part of a preschool block called Tickle U on Cartoon Network. There is a image of a poster which told you about Peppa Pig on Tickle U and when it would air and information about it.
You can also hear audio of the laughs of the Peppa Pig U.S. dub in the Peppa pig Tickle U website game, Swirlygig.
