Diane

Diana is the talking pet hen of Aunt Lydia and her side kick in Hotel Transylvania: The Series.

Powers & Abilities
Unlike most chickens, Diane is able to speak like a human with her clucks. As well as having some human skills and interests, like painting and putting on puppet shows for Lydia.

Since she is Lydia's minion, she'll most likely be an immortal like her mistress and the other monsters at the hotel.
