Fireballs are hazardous objects in the Croc series.
In Croc: Legend of the Gobbos, 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, Scorpions, and Firepoppers can also shoot Fireballs and Iceballs. These hazards seem to be the only hazards on Forest Island and Ice Island.
