Panel 1:
A new character waves to the reader with a curved stick arm. They float surrounded by smoke, wearing a long robe with gray shading. Like Tile, their head is blank and featureless, though they have a ponytail. They have no neck, head instead floating above their shoulders.
Caption: This is Theremin Grey.

Panel 2:
Close up of Theremin, holding up an arm which curves around the image of a frog.
Caption: Ghost of a frog enthusiast.

Panel 3:
Wide shot of Tile walking in-between trees with curling branches. Theremin Grey floats ahead, leading her. A curl of smoke trails along.
Caption: They know the way through the secret forest.
