Nuku Nuku comes from the anime OAV Bannou Bunka Nekomusume, otherwise known as All-purpose Culture Catgirl Nuku Nuku.

Nuku Nuku is depicted here in her school uniform. She's made out of soft plastic, about 8" tall and comes fully painted and assembled in resealable packaging. She's got no articulation.

Her base is a clear plastic piece that has a metal rod sticking out of it. You insert the rod into Nuku Nuku's foot to have her stand on the base. Be warned, the plastic of the base is fragile, and the weight of the figure will cause the base to crack and eventually cause the leaning seen in these pictures.

This figure can be had pretty cheap, about $10, but unless you are a diehard Nuku Nuku fan, skip it.
