Tumble's an enigma that few seem to be able to figure out. She simply appeared in Palleth one day with no explanation and proceeded to begin confusing everybody- including herself.

Tumble's DNA and dual-blood mark her as a Grem2, but Gremcorps actually initially tried to argue that she must be a cypherus since no other explanation made a lick of sense. They have no records of her, and her ears contain no tracker. When asked directly, Tumble herself claims to have no owner and also doesn't understand why anyone would want one. Even more perplexing, she seems to have knowledge of Palleth that is incorrect- but in a Mandela Effect sort of way. That is: the concepts are logical enough to appear true if not for the buckets of evidence suggesting the contrary.

Tumble can produce light from her hands that is almost hypnotic to onlookers. When touched by this light, people have been known to experience warmth spreading from the point of contact. Tumble has been claiming that the light is "lucky", but no one's been able to substantiate this concept with scientific proof. As such, it is simply listed as "mesmerizing light" in her file.

 Her confounding presence has caused several conspiracies to sprout up amongst those who know of her, and this isn't helped at all by Tumble herself finding the whole thing hilarious and playing it up whenever she can. She's claimed that she can fly and even once broke into the lab on a dare- feats claimed to be impossible by Gremcorps. She just. Doesn't care about anyone's logic. 

Tumble was likely flagged as kill on sight at one point, but the demand was retracted once the conspiracy theories started sprouting up. Now she's simply a cryptid that everyone is more-or-less forced to put up with. So fun!
