Sakura

"This is your zoo?"

Naruto saw Sakura Haruno entering the zoo through the front gate.

"Yes, it is," Naruto said.

Sakura sniffed. "Why is it empty?"

"I haven't gotten any animals yet," Naruto said.

"Ah, I see," Sakura sighed. She wandered over to an enclosure, which, thanks to the magic of the stone, was compelling her to go in it.

Sakura entered the empty enclosure, and soon, her clothes vanished as the enclosure began to change to match the animal she now was.
