Hazard

A hazard is an object or other Interactive Element which will cause Croc damage if touched or otherwise. These can be in the form of pits, for example. 

Pits

A pit is something which Croc may fall into which will cause him to drop crystals or lose a life. They come in these types:

Lava

Orange in colour, lava is found on Forest Island.

Freezing Water

Also known as Icy Water, this type of water is too cold for Croc to touch, let alone swim in. It is found only on Ice Island.

Mud

Mud pits are brown in colour and are found on Desert Island, although it is unknown why they would cause Croc any damage.

Acid

Acid pools are only found in circular pits on the Desert Island.

Cliff Edges/Bottomless Pits

Cliff edges are found on all islands and will cause Croc to lose a life regardless of how many crystals he has.

Fireball

An orange fireball which often comes up from a lava pit. Iceballs have the same affect which come up from freezing water. Some may also jump from pits onto the ground and jump back into the pit at the other end. Some may also juggle platforms to keep them above pits for a short time. Enemies such as Devil Dantinis and Scorpions and Firepoppers can also shoot fireballs.

Platform Pete's Platform

This type of platform is the only platform in the game which can directly hurt Croc. It is only found in Panic at Platform Pete's Lair and Crox Interactive. Platform Pete will hit his hammer on a switch causing the platforms to turn 180 degrees from a smooth surface to a spiky surface. 

Swinging Mace

Only found in some levels on Castle Island, these seem to swing from thin air and will swing from side to side, causing damage to Croc if he touches it.
