Crash Bandicoot 2: Cortex Strikes Back/Items

In addition to crystals, the items you can collect within the levels are:
 * Wumpa Fruit: collect 100 of them to get an extra life
 * Aku Aku Mask: a mask of the sorcerer Aku Aku follows Crash and protects him in case of contact with an enemy, dissolving but preventing him from losing a life. By collecting two masks, double protection is provided. On the third collected mask, Crash becomes invincible for a short period of time, then reverting to normal double protection.
 * Crash Icon: worth an extra life
