Fish to Fish

Thirty two tiles, each depicting a fish with five attributes ---- fin, eye, mouth, pattern, and color ---- are spread in a grid on the table. Each attribute comes in one of two states; eg, the mouth is either open or closed. A card is drawn that depicts two fish. Players try to be the first to draw and display the tiles that transform one fish on the card into the other by changing the state of one attribute at a time.
