Sunny Werewolf is the newborn daughter of Wayne Werewolf and Wanda Werewolf, and also the sister of Winnie Werewolf and the Werewolf Kids. She is a new character in Hotel Transylvania 3: Summer Vacation.
It is probably that she had being born in the time less between the second movie and the third movie.
Much like her siblings, Sunny has pale brown fur with darkish hair on the top of her head. She also wears a pink bow on her head with white polka dots.
Sunny is very calm and mature for her age. During her trip with her parents on the Legacy cruise ship she is shown to remain calm and focused despite her brothers screaming and crying right next to her. She has a tendency to bite.
She is shown to be calm, and passive, and also looking adorable. Although she has a tendency to bite others if they get close. She looks mostly like a baby, or a toddler, by the fact of being tiny, being charged, and been taken by her father. In contrast with her other brothers, she mostly never cried, instead she smiles cutely. Another hint of her being a toddler is that she just says two words during the film, which are Fish and Boat. So she can barely talk.
Sunny appeared at the wedding that begun after the prologue of the Movie, she could be seen on Wayne's chest, acting calm around her brothers, she then bites Frank's finger once it got close to her, thus making Wayne joke about it. she is later seen on the cruise around her brothers when her family were taking a photo, Since then, Sunny only appeared on Wayne's chest, when the werewolf family arrived to the kid's club, Sunny was dropped off there, along with her brothers.
- Like her sister Winnie, she is well behaved (although she does bite)
- So far Sunny is the only werewolf pup whose name doesn't begin with a W (though it’s likely some of the other kids don’t)
- Coincidentally she shares the same name with her voice actor.
- Sunny only spoke one word in the film. (Fish)
- At one point in Hotel Transylvania 3, Sunny could be seen sucking on a pacifier that resembles the one Winnie used to have, however she was never seen with it ever again in the film.
