Whoa Nelly! The existence of Emerald Cyclops(es?), initially claimed by Maxwell, has been confirmed by myself and Spacerx in a mysterious underground cave. They came out of nowhere it seems - such was their appetite for destruction that we had to slay them before they escaped the cave and lay waste to the world above.
Unfortunately none would allow themselves to be taken alive and thus no specimens are left for the Britannia Zoo - hopefully we've not caused their extinction! But if not, from whence did they come? T'is a mystery as no more have appeared...
