Night (1930)

A spider sneaks in to a toy store and sees the toys come to life as he plays a tune on the toy piano and record player.

The title pretty much says it: fish and other marine life dance and frolic to various tunes. An octopus keeps spoiling the fun in various ways.

One day in the life of cannibals with a gypsy soul and lion-chef.

The demons of hell play music for Satan, whose delight turns to wrath when an insubordinate refuses to become food for Cerberus.

The monkeys are swinging; their song and dance routine has other jungle creatures joining in. And two monkeys in love chase and kiss. But the hungry crocodiles lie in wait (and dance the soft shoe)...

A collection of arctic animals (seals, walruses, polar bears, penguins) float by on ice floes and on shore, performing various musical numbers.

The bugs of summer frolic and dance.

The season series of Silly Symphonies continues, with squirrels storing nuts and corn, crows stealing it, beavers building a dam, ducks migrating, and the like, as the first snows fall.

Flowers, insects, and a crow family all dance to a jaunty tune celebrating spring. After a brief storm, grasshoppers, frogs, and spiders cavort to the Dance of the Hours.

A Spanish cantina. The toreador enters, sees the waitress being harassed, and confronts the military/police type doing the harassment. She comes to the bullfight.

The clock strikes midnight, the bats fly from the belfry, a dog howls at the full moon, and two black cats fight in the cemetery: a perfect time for four skeletons to come out and dance a bit.

In the last of the Silly Symphonies season cycle, bears hibernate (or try to), raccoons sneeze, moose swim, and pretty much everyone ice skates. Everyone gathers around the groundhog to see what happens.
