Twilight of the Cockroaches(ゴキブリたちの黄昏)

A messy bachelor's apartment is a paradise for the huge colony of cockroaches living there: no sprays, no traps, and plenty of food. When the homeowner's girlfriend moves in, however, the party comes to an abrupt end, and the roaches must quickly adapt to a life of struggling for survival. Combines animation with live actors.
