A clean and safe environment is important for everyone and everything, including frogs like those you see in the game below! So if you like frogs and want to help study and protect them, please visit:

NIEHS Kids: Are frog "deformities"an early warning sign?	My Health My World Activities
FrogWatch USA (Where YOU help scientists!)	US Wildlife Federation's Endangered Wildlife

Your mission is to see how quickly you can switch the frogs to the opposite side of the picture. If you get stuck, you can start over by clicking on the arrow () in the picture below to return the frogs to their starting places. Don't give up until you figure it out!
