Level 4
Feel the red metal box water in order to move the gears. Use small lines to carefully redirect water first to the red box with the diamond and funnel and then the blue box, once the gears are opened, swipe to let the water fall to Swampy.
Level 4, part 2.
In part 2 of level 5, you need to AVOID gathering the duckies! In order to do this, you’ll need to slowly divert away and let it trickle a little more. Start by making a small triangle on top to slow down water flow. Let the water gather in the tunnel right next to swampy, as the level rises, make a gap for the blue metal box but not too large or you’ll get that ducky on the left hand side!
