If Taz picks up Bugs when acquiring Babba's token in the Genie Temple, Bugs can get stuck and fall through the desert and land at the beginning of the Arabian Era.
If you want to save the game at "Transylvanian 100%", you must pause and save the game after completing either Zoovania or the Haunted River but before exiting.
In the Arabian Era, if Taz has the view when going to Tweety for help, Bugs will fall from the sky while saying "What's up birdy?".
