I'll show you who's the smartest creature on land and the sea. Now you need to swim out into the sea. The monkey leapt into the sea, and swam about merrily for several minutes. But soon, the undertow pulled him deeper into the ocean, where he quickly drowned. The dolphin rolled back into the water, nudged the waterlogged carcass of the monkey onto shore, and then swam off into the depths, victorious.
