Park Bunny (or Misty Bonnie as I like to call her as a nod to the Short she appears) was a sexy looking one time miscellaneous character that briefly appears at the end of the 1976 Pink Panther Short "Mystic Pink" ( https://www.youtube.com/watch?v=MhHJbGV5aWQ )

In the short, Pink Panther finds a Top Hat, belonging to Mysto the Great, which fell off from his van when passing by; Pink takes the hat and from it a Large Magic Big Bunny appears and clings on to him, but to his misfortune, Pink is force to be stuck with the Rabbit as is require by law to have a Pet license, as inform by a Cop (The Little Man in one of two appearance in the short, the other been a Manager of a Health Spa), and while the Big Bunny tries to be helpful to his new Pink Pal, these end in a fail Oil Excursion to a disastrous day at the Spa. Finally his troubles come to an end when the two pass by a gorgeous looking Bunny at the park and the Big Bunny tries to give her a bouquet of Flowers; unfortunately, our Big Boy here is a Married Bunny and Mrs. Big Bunny comes out, roller-pin in hand, and their little Bunnies following, forcing the Park Bunny to ran off from harm's way, while Mr. Big Bunny runs from his wife and kids; in the end he comes back to Pink to get the top hat and brings out Mysto's Van from it, he jumps into the hat and the Hat jumps into the Van, and takes off, with the rest of the Bunny Family going after him in Hop Pursuit.

Despite that the troublesome Bunny is out of his Pink Hairs, Pink gets in one last mess when grabbing a Rich Man's Top hat, trying to pull tricks out of it, but ruining it; Pink then runs back to his house at the Dumps chase by the Rich Angry man.
