Dtz enjoyed planet Earth so much that he decided not to return home, so while Brik and Brak returned to Fleeblebrox in their starship, Dtz secretly escaped back to Earth in a shuttle craft. When his friends went back to look for him, Dtz assumed the form of Dale, an Earth squirrel, and changed places with him for a while. Dtz was finally convinced to go back home when he was offered a plate of delicious Irkburgles.
