Backpack Buddy

Little Snap enjoys riding in backpacks or in ways it can be carried on a friend's back. While riding in a backpack, Little Snap also benefits from Territorial.  

Territorial

Little Snap can designate a creature it can see within 30 feet to be under its protection. When a hostile creature moves within 5 feet of a creature under its protection, as a reaction, Little Snap can immediately make a Bite attack against the approaching creature if it is within range.
