They appear similar to normal dark creatures, but they have a golden helmet (or shell) on their backs. On the shell are many grey spikes.
Like other dark creatures, this enemy can jump through platforms. It is very similar to the helmet dark creature encountered in the good levels, but unlike the helmet dark creatures, it will not lift up its helmet. The bottom of spiky monsters is their only vulnerability, and to kill them they need to be lead on to hot rock. Spiky monsters could be considered the "evil" variation of helmet dark creatures.
