In the middle of breakfast...

In the middle of breakfast this morning, this random conversation occurred:

Maya (surprised and all of the sudden): "Where'd the kangaroo go?"
Tim: "What?"
Maya: "Where'd the kangaroo go?"
Tim: "What are you talking about?"
Maya: "Did he go home?"
Tim: "Sure, he probably went home."
Maya: "He's having breakfast."
Tim: "OK, Maya."

(After a bit more questioning, which included asking Maya when and where she last saw the kangaroo, we realized she was talking about the wallaby they had at day care several weeks ago. What made her think of it, we have no idea.)
