Peppa Pig is a British Preschool animated series. During circa 2002-2003, a pitch pilot was made and pitched it to Nick Jr. UK and Contender Media. Only one piece of footage was found on an Australian promo for Nick Jr, where one clip shows where Peppa lays on the floor, giggling.
We have nearly no info about this pilot. Well, it's lost, yes, but nothing really besides the possible screenshot above.
