Mickey's Pal Pluto

The story

Pluto rescues a bag of kittens from the river. He feels rejected, then, as Mickey ignores him and blames him for damage the kittens do. His angel and devil sides argue with him. Pluto gets thrown outside. The kittens also find their way outside, and fall into the well, where Pluto's angel side wins out as he rescues them once again and is finally recognized as a hero.
