Note: This level is first available after the "Mystical Munkeys" level if and only if you have at least 100 Electoons (which means you must have successfully collected about four-fifths of the Electoons up to that point).
In this video, I show you how to obtain the Skull Tooth for the "Tricky Treasure Temple" Tricky Treasure level of "Mystical Pique". Have I mentioned that there's a Tricky Treasure here?
This one is far easier (though more beautiful) than the last Tricky Treasure level, but it still has its difficult moments.
0:51, I think, is proof that you can't open Tricky Treasure Chests prematurely. Try it out yourself!
