So a couple of years ago I saw this film. It was a cartoon but I don’t think it had any dialogue. And you’d think that this would narrow down the number of titles, but apparently not. So anyway, there’s this baby boy in his house with his parents then his parents go to another room or something. He takes a hot air ballon to I think 3 different places (not places in the world, more like different “lands” if you know what I mean). He meets different creatures along the way and befriends them. At the end I think he says goodbye to them and goes back home.
