Yuffie liked Transform materia. It could come in handy. And the Shrink and Toad spells were just the most simple ones to use.
Yuffie was bored, and knew some others...
And so, Tifa found Yuffie laughing at an irate red cat, with a scarred right eye.
"I couldn't figure out if he was a cat or a wolf. Problem solved!" She laughed.
"Yuffie, stop abusing materia like tha-" Tifa began, only to be cut off by transforming into a black tabby.
"It's just a prank, Tifa, don't be so catty about it!"
The cats hissed angrily, and pounced.
"AAAAGH! CLAWS!"
