Note: This level is first available after the "Dashing Thru the Snow" level if and only if you have at least 70 Electoons (which means you must have successfully collected almost all [≈93%] of the Electoons up to that point).
In this video, I show you how to obtain the Skull Tooth for the "Sink or Swim" Tricky Treasure level of "Gourmand Land".
Here's another easy Tricky Treasure. I think you're better off avoiding slides and such when the opportunity arises. Plain old sprinting should be all that's necessary when you need to move quickly.
