In Noki Bay, the first episode, HOW DO YOU BEAT IT?

Climb up the sea shells and then go up all the ramps, I may be thinkin of the wrong place but if its when you have to unplug the waterfall I'm not wrong.

Uncork the Waterfall

This episode's objective is to destroy the Mole in the cannon that's firing the goop all over the place. Even worse - he's doing it from a cork in the waterfall at the top of the level! To reach the top of the level and the Mole in the cannon - you're going to need to head to the right side of the level and go up and up and up - so - from the start - head straight across the several platforms in the water. Continue to the shaded platforms that act as steps leading to the top. Next - jump onto the basket above the ground - jump and hover onto the next ledge.

Hover across the next pit while avoiding the goopy balls from above and clean off the symbol on the wall to reveal a new ledge for you to jump on. Use it to reach the next ledge - then hover over to the next one. From here - hover across another large gap - and clean up the mess on the platform there. Then - continue to an arrow sign pointing upward. Stand on the hanging platform and spray water into the cracked jug in front of you. Doing so will raise the platform that you're on. At its highest point - turn around and jump - then hover over to the higher ledge. Go up the hill - cleaning it off
so that you don't end up sliding down it. At the top - jump onto the giant wheel and then hover over to the top platform.

Up there - jump to the wall and wall jump. Then use the Hover Nozzle and get onto that high ledge. Go up the path and spray that springboard and it'll become compact size for you to carry. Drop down to the lower ledge with it and drop it by the high wall. Bounce on it to reach the top of the wall - then continue onward. Jump up the steps and wash off the top ledge - and the Mole in the cannon sitting atop the cork will start throwing timed Bob-ombs at you. Spray them and start throwing them back at the cannon. When you make a direct hit - it'll be over and the waterfall will be uncorked. Take the Shine that appears!

Right, on your way to the top try to avoid the goop that the mole is shooting at you.

Try not to use your water unless absolutely necessary because you won't find a body of water until you're near the top which is a long way up if I say so.

When you eventually get to the mole in the cannon fight it as you did in Pinna Park:story two.

If you haven't done that then throw the bombs at him when they turn blue.
