From the publisher: Players must use the Lily Pad Launchers to spring their frogs toward the rotating tree to see who stays and who falls. Whoever has the most frogs left in the tree wins that round. Includes 24 frogs, 4 launchers, base, tree trunk with tree top and 4 tree limbs and instruction sheet. Requires 3 "AA" batteries. The flexible, rubbery plastic frogs are shaped to hang easily from the tree branches, but when the branches pop up, these little amphibian friends tend to go flying. The brown tree trunk and blue game base are made with a sturdy, durable plastic. The green branches are made lighter for extra spring when the frogs land -- and when time is up. The lily pad-shaped catapults work really well -- so well, in fact, they'll fly too if you don't hold them down with a finger.
