Not to be confused with Harmony, the character in Toy Story 4.
Harmony is a major character in the TV series Sing Me a Story with Belle. She is a yellow cat who is sleepy a lot of the time.
Harmony does not like hard work, but expects the reward (such as Belle's chili in "Reap What You Sow"), and is known for taking the easy way out (same episode and "Taking the Easy Way Out"). She is also afraid of ghosts ("Sleepover").
Despite being a female, she is voiced by a man named Jeff Conover, making her one of few such characters.
