TOKAN

From BoardGameGeek:

A tactical skill game for two players. Each side has a team of lions, jackals and mice. The animals meet randomly and, as the game field changes, they must win through thanks to their tactical abilities. Winning relies not on taking away but covering a piece. The top piece reveals the owner of a stack; all the rest underneath are “gobbled up”. It's unlikely in the wild, but possible in TOKAN: the mouse can also eat the lion! Only the smartest creatures will survive... -description from the publisher
