Pikiinya! takes the Tetris-esque formula of blocks falling from the sky, and adds gyrating tropical-type penguins. They excite easily, and sleep when they are alone and/or bored. These penguins just want to live in peace, and throughout the story mode in the game they must constantly fight against people that want to capture them including poachers, witch doctors, and mad scientists.
There was also a mobile version of the game released on what looked like a virtual pet key chain thing, which was supposed to be a promotional item with the game in LCD format, but it didn't do too well. ASCII were planning on making it a franchise but the timing happened to be wrong.
The soundtrack was also released as part of a best-of ps1 compilation album.
