Usavich

Usavich (ウサビッチ, Usabicchi, from うさぎ "usagi", Japanese for rabbit, with "vich" to make it a Russian patronymic?) is a series of animated short films originally created for MTV's Japanese mobile service "Flux" and still being created for MTV Japan by Satoshi Tomioka and his studio Kanaban Graphics since 2006. It is about an odd pair of rabbits imprisoned in a Soviet prison. While the first season shows the absurd everyday occurrences of the two rabbits' prison life, and since the second season they go on the adventures of escape and life on the run.
