We followed the children's trail to the forbidden ruins; the place that parents from all the nearby tribes warned their young ones to never go near. It was once supposed to have been some sort pleasure land for the Ancients before the Great Cataclysm, now it was a place of whispered horror where none ever returned.

The party first saw it come out from behind the a rusted-out metal shed--I swear by the Lords of Light that there was nothing there before! It looked like some misshapen Hoop or Hopper, but larger. It stood upright and walked like a humanoid rather than hopped. As it approached, I could sensed the thing exuded a dark, evil, inimical intelligence, but not a word it spoke. It only laughed... <sob> ...by the gods! How it laughed! It was a laugh that chilled my soul and filled me with more terror than I had ever felt before. I can still hear it now...

 No one knows where these horrors come from or what they truly are: some insane mutation, a demon straight from the depth of Hell, an Elder God from a realm of madness and chaos beyond space and time? It is always found in the ruins of ancient theme parks. It seems to have a fondness for child flesh, a prey that is easily lured its doom by it's whimsical appearance. That is, until it's ready to feed.

The creature appears to be mute, save it's constant, spine-chilling, fear-inducing laughter. The creature generates pure paralyzing  knee-shacking, bowl-and-bladder-loosening terror. When it's prey is sufficiently petrified by fear, it lashes out with it's razor sharp teeth and claws. It is also reported to have teleportation abilities, appearing suddenly to attack. Some brave and fortunate warriors have reported slaying this beast and finding hordes of Ancient technology among the bones of childern in its lair. However; it is soon replaced by another or it returns from the dead. No one knows for sure!

Here is a segment of the only known video documentation of this monstrosity:
