Adventures in Wonderland
The Day of the Iguana
S1 E65:
After the Queen banishes a phony fortune teller from the palace, Rabbit fears her majesty will be the victim of retaliatory hocus-pocus. His worst fears are realized (or so he thinks) when an iguana escapes from the fortune teller's menagerie and finds its way to the Queen's throne...convincing Rabbit that the monarch of Wonderland has become green, scaly, and a climber of trees.
