 Crash 's primary abilities are jumping and spinning . Most enemies may be defeated by jumping on them or spinning into them . An enemy that is attacked by Crash 's spin attack can be launched into another enemy that is on @-@ screen at the same time . These same techniques can be used to open the numerous boxes found in each stage . Most boxes in the game contain Wumpa Fruit , which give the player an extra life if 100 of them are collected . Another item found inside crates is the Witch Doctor 's Mask , which shields Crash from one enemy attack . Collecting three of these masks in a row grants Crash temporary invulnerability from all minor dangers . Arrow boxes ( marked with arrows pointing up ) propel Crash further than his ordinary jump can , while TNT boxes explode after a three @-@ second fuse when jumped on . Boxes with an exclamation mark ( ! ) on them cause previously intangible objects in the area to solidify . Check Point boxes allow Crash to return to the point where the first Check Point box has been opened upon losing a life . If more than one Check Point box has been opened in a stage , Crash returns to the last Check Point box that has been opened .
