Ishii Hisaichi no Nanda Kanda Gekijou

Ishii Hisaichi's comedy anime collection features a main story about the Underground People's repeated attempts to leave their crowded cavern and take over the surface world, with mixed results. The anime also includes the episode "Christmas Aid," where a popular group called Yukadan sets the Undergrounders' second escape attempt to music. Two unrelated shorts, "101 Ninja" and "Ken-chan's Space Exploration Adventure," are also part of the collection.
