Infinite Wumpa Glitch

The Infinite Wumpa Glitch is a leftover debug feature that constantly gives the player wumpas when a bodyslam is lasting for too long. This can be done using a cutscene, a Spring Crate for instance. The wumpas come at a rate of one per frame and they stop shortly after Crash's animation is updated. Its main use is to get a lot of lives quickly.

Methods
Before every cutscene in which Crash can enter a temporary T-pose state, start a bodyslam at the edge of the cutscene trigger so it is interrupted by the start of the scene. In some cutscenes the effect happens right after the interruption while in others it is needed to wait quite a long time after the end of the scene for some reason. The other method works by doing a bodyslam under a Spring Crate with a precise timing. The effect is immediate, but Crash's idle animation will interrupt the glitch shortly after landing and dying will interrupt it as well. Another thing that can interrupt a bodyslam is getting in the permanent T-pose state while performing a slam.

History
In 2012, Jokerer4 got that glitch after bodyslamming before the cutscene at the end of the Doc Amok section of Bandicoot Pursuit. In May of 2015, Bandicraft rediscovered the glitch by bodyslamming on the frame of the door and triggering the cutscene at the end of Classroom Chaos from the wrong side. A few days later, Smartkin made a video showcasing the glitch, showing that you may have to wait to get it. In December of 2015, Crafis made a video showing the glitch happening in Rooftop Rampage after a bodyslam is interrupted not by a cutscene but by getting in the hard T-pose state. Gpro got it using Spring Crates in High Seas Hi-Jinks.
