Yiff! Hot

Yiff! is a puzzle game for two players (or 1 against the computer). The two take turns placing foxes into 'rooms' on the grid. After a certain number of foxes fill a room, they change color and scatter to adjoining rooms. The object is to change all foxes to your own color. A pair of Street Fighter inspired fox-morphs battle out the combos at the bottom of the screen.
