You were experimenting with your new spell when suddenly your friend, Elaina went in

"... Hey, what do ya want for lunch-"

Your spell hit her, but you don't know what it can do. In an instant, cat ears and tail appeared on her body

"Hah?... What's this... Her cat ears twitched while she's trying to process what just happened

"You... Hmph..." She scoffs while crossing her arms and turning away from you "... I'm not gonna let this slide..." She said while her tail swayed side to side
