Just fill out the bio and follow the instructions to join the rp! :) You can use other lineart for the cat, but make sure you show the left and right sides and give credit to the artist if it's not your art!
Lots of thanks to -Winterstar- for inspiring me to make a Warrior RP! Link to the studio! ---> https://scratch.mit.edu/studios/4186087/ (You may need to copy and paste it!)
