I've been trying to remember the name of a cartoon I watched around 2010 about a dinosaur that eats clouds. He lives on the clouds and comes down during the day, where he meets his friends, and one of them was a pig, unless I'm mistaken. He is pretty big and I vaguely remember his friends using his tail as a slide as well.
I'd appreciate if anyone could help me out here!
Update: I think it's a dragon.
