Peter Brown, is a charming children's book about a tiger who has grown tired of the very proper and conservative society in which he lives. He looks very dapper in that top hat and bow tie, but Mr. Tiger just wants to be free. When he finally starts acting on this desire, however, his friends and neighbors aren't so happy about it, and he has to leave the city.
Just from this, it sounds like kind of a sad story about intolerance, but Mr. Tiger Goes Wild has a nice ending. The wild turns out not to be as great as Mr. Tiger expected, and he returns to the city, presumably resigned to resume his previous conformity to the society's rules about behavior and fancy dress. To his surprise, though, all his friends and neighbors have apparently decided maybe Mr. Tiger had the right idea (to an extent) --- everyone seems to have found a nice balance between being proper and being wild, and they welcome Mr. Tiger back with open arms (open forelimbs?).
