Aah is a monster and Roar's love interest appeared at the end of "Frankengloom". Introduced by Queen Delightful, Aah was created by Doc using a Make Your Own Monster Kit for Roar to keep him company after the 7D helped him preparing his overall appearance to pass an audition to enter Do-Re-Mi Academy as well as defeating his creators, Hildy and Grim.
Like Roar, Aah is reptilian-like, but she is olive green-skinned with webbed hands and purple fingernails. There are two large pink fins on the top of her head and a tail on her rear. She also has huge red lips and wears a pink skirt.
