The Slider event for Wumpa Village is one of the few Event levels that need to be visited twice to collect all the Tiki Masks in it due to forked paths that both contain collectibles. If you keep holding UP+LEFT from when the countdown of the level starts, then hug the left wall, and after that turn to the right just as the penultimate piece of mojo before the first pit moves off-screen (see picture for reference), your Pandebra will die from falling into the pit rather than dying from crashing into a wall. After the Pandebra dies, you regain control of Crash and if you've been holding UP+LEFT this entire time, he will just be able to grab the ledge. You will now have free control of Crash for the remainder of this level (albeit in a slightly glitchy way), allowing you to collect everything in one visit. Crash moves slower than the Pandebra but not having to revisit the area still ends up saving ~20 seconds.
