Mikey thought some more, then came up with an even better idea. With this one, Zelda could remain as herself and they would get Athena back to normal.
"I could use the stone to wish up another pendant," Mikey said. "Then we'll use the second pendant on Athena."
"Actually, that sounds brilliant," Zelda said, handing over the stone back to Mikey.
Mikey grasped the stone and said "I wish that I had a duplicate of the pendant necklace that Zelda is wearing right now and that it would function exactly the same way."
The stone glowed and suddenly, Mikey was holding a necklace in his other hand. It looked exactly like the one around Zelda's neck.
"Now, we just need to find Athena," Zelda said.
