The stars come out to the Hollywood Bowl for a night of musical fun.

Peterkin, a mischievous elf with mixed body parts, decides to see what would happen if he switched the eggs in the tree-maternity nests. What happens is that there are many surprised mothers, and just as many indignant fathers, when the eggs hatch and each family gets a hatching that resembles neither parent. All fly the, figuratively-speaking, coop and Peterkin is left to tend to all the young birds.

Santa Claus gets a telegram from Oswald the Rabbit, telling him the city is ready for his Toyland Parade and that there will be a reception in the big department store. Santa is a jolly elf indeed until he discovers that moths have eaten every last shred of his Santa suit. The day is saved when quick thinking on the part of an old elf, armed with red paint and popcorn, turns Santa's ordinary light-blue outfit into a real Santa suit. The parade is a big success, and the reception promises to be even better. Frankenstein's monster, Tarzan, Lupe Velez, Shirley Temple, Al Jolson and Bing Crosby are all there to greet Santa. Laurel and Hardy nearly spoil the day when they dress in a dragon's costume and try to steal the chocolate cake.

A comical twist on the history of America.
