Nobody realizes that buried deep beneath the surface of Earth's hot bubbling mantle is an entire race of strange wily creatures known only as "Lava Bunnies"!
Nah, that's really just Erin. As a sort of hobby, it's fun to see where we can fit her. "Look, a crevice!" we might cry out. "Let's stick Erin in there!" "Look at the size of this cabinet," we might proclaim. "We could put four Erins in here!"

When she's in a cooler mood, Erin'll just hang out and be cool and detached. It's her crazy Clan ways, I suppose. We don't question them, we just make sure that there are no live animals or particularly fragile egos nearby.
Erin spends an inordinate amount of time honing her near-perfect impression of Homestar Runner.
