The structure is...odd. Like a dinosaur, if the head was cut at the base of the neck and replaced with a clock. But there is an entrance- on the underside anyway. It requires a good hop for most children to get in.

...Older teens with enough height could just stand and look up through the hole, however. And what's in there isn't much. It's rather dark- but the girl stands out significantly. First glance would say the girl is wearing scrubs- but these aren't quite hospital scrubs, not when there's a definite collar alongside it all.

She turns slowly to the sound- or even lack of sound- of the other's presence and stares, blankly and widely.
