Helmet dark creatures

Helmet Dark Things are enemies from the Twin Shot Series. They are actually only Dark Things wearing Spartan Helmets. They can only be destroyed by shooting them when they lift up their helmets, which is not often. There are two variations; red feathers and blue feathers. Red ones walk and jump at the same speed as a normal Dark Things, and Blue ones walk and jump faster.

Nitrome Must Die
In Nitrome Must Die, the Spartan Helmets are replaced with Construction Helmets, helmets much like the ones worn by the Demolition Crew in the Rubble Trouble Series. Helmet Dark Things have the same behavior as in the Twin Shot Series; it walks and jumps, then after some time lifts up its helmet. They can also be shot when they are falling off a platform, as they use there helmets as a parachute. They are completely invincible when there helmet is on them, being only able to be harmed when they lift up there helmet and are falling off a platform. They appear in only one level of level set 21-30 and 31-40, the level in each level set being the same.
