A fisherman wants you to uncork the waterfall. Go up across shells to basket, shoot water into jar. Head up by washing off walls. Another basket and jar. Be sure to shoot in wall squares. and wash off any symbols.

Now you'll get up to a ramp area. At the top of the ramp is an up arrow sign. Balls come down in sets of 3. Wait for 3 to come through and then wall-jump back and forth in the chasm to get up to the top.

Warning, the square on the right up here has a monster in it with the coin! Now you'll meet a guy in green and black. He's the student of grandpa. He gives you a springboard - spray it to shrink it. Jump down to the lower area with it and put it by the far wall. It'll get big again, jump up to near the bomber. He'll throw bombs at you. Spray one to disarm it, then throw it at the guy. It'll blow out the cork, and a shine will appear over your head!
