Mine

Mines are hazards that first appear in Crash Bandicoot 2: Cortex Strikes Back.

Crash Bandicoot 2: Cortex Strikes Back
The first type of mines appear in the river levels where if Crash hits them he falls off the jet board and drowns unless he has an Aku Aku. Some of the mines move, making it harder for Crash to avoid them.

The second type of mines are land mines. When Crash steps on land mines, they send him flying into the air, temporarily stunning him.

Crash Bandicoot 3: Warped
Mines appear as hazards in the underwater levels of Warped. They are attached to chains and follow Crash's movements. Shooting a missile from the submergible at the mines is the only way Crash can safely destroy them.

Crash Bash
In Crash Bash, they are a special item found in all of the Tank Wars arenas, including the boss fight with the Komodo Brothers. A player can drop mines which will explode after a few seconds.

Crash Bandicoot: The Huge Adventure
Mines once again return in the underwater levels. Unlike their Warped counterparts, these mines are not attached to anything. In addition, they move quicker, making it harder for Crash to safely pass them.

Land mines also appear in the chase sections of Frostbite Cavern, Snow Crash, and Snow Job. They send Crash and Polar flying into the air, stunning them.
