In Terville a large frog is looking out of the water. He tries to catch the flies with his long tongue. So beware you do not get eaten, he may well think you are a fly.
The landscape around the frog allow you to move around freely. You can either jump into the water and swim around among the water lilies or you can try to save the sinking rowboat on the water. If you do not want to get wet, you can just jump around on the water lilies, climbing cobwebs or walk along the cabins on the bridge.
If you are brave you can try to climb upon the back of the frog and slide down the long tongue.
