Polar Paradise
Walls	No
BG Music	Frozen Paradise

Polar Paradise is a stage in Tekken 5. It is a polar stage, and there are penguins and a few seals all around the fighters. The fighters and the animals are on a huge block of ice that is above a big body of water. The sky has some clouds in it, and the sun can be seen in the sky, too.

Note: Sometimes, if you fight too close to the animals, they will slide away to safety, much like the Poolside stage.
