Up the Creek

Up the Creek is the first level of world 3 in Yoshi's island DS. The level mostly takes place on a river. The enemies are fish, lunge fish, and egg-enuts.

In the first part, the player has to overcome some Snapjaws to get to the second part, where Yoshi encounters a Nep-Enut (the only one in the game). Then, there is a part where Yoshi has to get on a raft to avoid falling into the river. If he did, a Lunge Fish would swallow him almost instantly, making Yoshi lose a life. Then, after the raft falls off a waterfall, a self-scrolling part will follow in which Yoshi has to get to the top of another waterfall.
