Has anyone considered that Scooter, (aka Orange Guy,) might be multiple creatures?

Let's assume a rogue group of goblinoid, um... rogues... which live among the bugbears and which actually work for Serinni or her appointed gate guardian, (Boss.)

Halfling Rangers who are disguised as goblins would also fill the bill. In this case, Serinni may have recruited a corps of rangers to supervise the gate's defense. This would allow them to move around unseen and leave no tracks, even in snow.

So. I propose Serinni has left an arctic druid and a cadre of rangers as the gate's ulthmate guardians, and may in fact be Kermit.

The green speech bubble may be explained by the possibility that she is shape changed or otherwise magically altered either as a disguise or to extend her lifespan.
