Werewoof dads! Well, one of them is anyway.

People who have a parent from the Wood can turn into a hybrid of whatever animal their parent was and whatever species the other parent is. They usually have complete control over when shifts occur except during a full moon, in which case they undergo a forceful transformation into their hybrid state. Randy would take a werewolf form to help his kids to learn about that aspect of themselves while growing up. They all knew he was actually a wolf from the Wood rather than an actual werewolf, but it helped to have someone who at least looked like them.
