The very end of "The Mad Doctor" after Mickey wakes up, Pluto comes into his room and licks him. That was quite refreshing.

The plot of "Pluto's Fledgling", in which a bighearted Pluto tries to help a baby bird learn how to fly.
The ending to "Puppy Love". Mickey had just broken up with Minnie after a misunderstanding and swears he'll never speak to her again. Yet when Minnie, who had now realized the truth, calls for him, Mickey is instantly happy and rushes over to her with Super Speed.
The ending to "Fathers Are People". Goofy (in his George Geef personna), who had been dealing with Junior's antics throughout the picture and is just about to give him a thrashing when Junior leaps out of his crib and hugs him.
