Enemy Wraparound Glitch

From Glitches

From the game Magic of Scheherazade for the NES.

If you push an overworld enemy up off the top of the screen with your sword or rod, it might reappear in the menu area at the bottom of the screen. This is easiest to do with the giant Antlions that leap around in the desert areas.
