Marsupilami S04E06 - The Hidden Ear

Hector, Marsu, and Toofurkey walk into the Vin San Gogo ghost's forbidden territory while playing, despite Toofurkey's warning beforehand. In their high spirits, Marsu and Hector knock over the totem of the spirit. The three put it back up, but now the totem is missing an ear. Shortly thereafter, one realizes that all the birds have become mute. Topangadakota says that Vin San Gogo in his anger silenced the birds, and if the ear is not found and the spirit is appeased with a musical ceremony, then the other animals follow, and then the humans, and it all eventually leads to the end of the world.
