"What kind of cave is this, Tessa?"
"I don't know, Stuffie. But it sure looks like someone lives here."
"How do you know?"
"First, from the chalk drawings on the walls..."
"They're pretty cool."
"Second, from the light coming from that side passage."
"But what if we found the home of a pencil tiger or an eraser bear?"
"They wouldn't be drawing on the walls or using light."
"You're right, Tessa. Then let's go in!"
