There was a show I used to watch when I was little. I can barely remember it. I know it had to do with cartoon animals that wore clothes (maybe sweaters) with numbers or something on it. There were two children and I think they had to learn a lesson or do something for each animal so they could pass on through a door or some kind of portal to the next. They were trying to get somewhere. I think one of the animals was a lion but I am not sure. Can anybody help me?
