This movie is very didactic, but it is not for toddlers. They show you that you can love someone even though you are very different. It shows you that bad things do happen in life, not like Hollywood movies where everything is "pink".
The music is excellent too!.
Excellent movie!!!!! I love Leafie, and of course, Greenie. And his dad! And the funny sea otter, and the frogs, and the bat.... all the characters were great.
