In one episode, she began to show signs of evolving, but resisted the glow and stopped herself from evolving much to Azusa's confusion, she later explains to her that she is happier as she is as a Purrloin, and evolving into a Liepard would make her look scary for Azusa, Azusa herself was on the verge of tears hearing Azu-nyan's story that Azusa decides not to evolve her, much to Azu-nyan 3's delight. As a result, Azusa gave her an Everstone charm on her neck so she'll stay Purrloin forever.
