Level 5
This level is pretty easy! Make sure you first aim water for the most top ducky and then work your way down. Don’t forget–in order to move the gear mechanisms, you need to “fed” the metal box water.
Level 5, part 2.
In part 2 of level 5, you need to avoid the ducks! Divert the water mostly to the left and leave a small amount for the right hand-side to feed to the box.
