Zap has a reason to accompany Fabi on her journey than just to prevent loneliness.

Anyways, Fabi actually wears speed boots which can be super-charged by hyper-go-ons. Not to mention her gloves and jacket can absorb them too.

EDIT: Oh, and I added a few changes to Fabi's design to make her look more like an actual wolf (slightly smaller ears, smaller tail, and a change to the snout which you'll see at some point).
