In the first three games, a glitch can be performed when bouncing on multiple enemies consecutively. Normally, by bouncing on 5 enemies in a row, you get an extra Life in addition to 3 Wumpas from the previous 3 enemies in that combo. However, the bonuses that come from bouncing combos go further beyond that into triple-digit combos as a result of there being no set combo limit. This means if performed correctly, triple-digit combos can overflow the item table to give key items that you are not intended to get through them including Tokens, Crystals, Gems, Sapphires, Relics and Powers.

This can be achieved through tool assistance or through human play by building up the bounce combo on a respawning enemy or more ideally an Iron Arrow Crate, and then continuing the combo on enemies to start reaping these items. Preserving a bounce combo can be done by spinning and crouching right before hitting the ground, as the combo count is lost when Crash enters the standing or walking animations.

The attached image features a list of items that can be earned through this glitch, as well as the requirements for glitched higher percentage runs of each game, created by speedrunners dass and ThaRixer, the latter of whom originally utilized the glitch to dramatically lower the speedrun record of Crash Bandicoot 2: Cortex Strikes Back in 2012.
