To beat the level as well as tri-ducking it, first dig through the dirt to carry the water to the red switch to open the red gate, making sure you have enough water left on top to get the duck behind the gate. Once the red gate has been opened, guide the leftover water to what is the first duck. Once done, guide the water that was carried to the red switch down to the second duck, and then quickly to the green switch, opening the green gate. Once the green gate is opened, guide the water to the last duck over the shower pipe, making sure it doesn't touch the algae. Finally, guide the water to the shower pipe and the level will have been tri-ducked.
