Crash next to an Inflating Cactus.

Inflating Cactus are enemies in Crash Bandicoot: The Wrath of Cortex who only appear in Gold Rush. When they move, their spikes extend and they inflate, making them invincible for a few seconds. When in this mode, they can't be defeated with any move, and if Crash attempts to spin or slide into them, they will knock him back. If Crash jumps on top of them or a Belly Flop is attempted, he will lose an Aku Aku mask or a life.
