So many questions:
- Fluffy hooves are soft (in most headcanons). They can’t have possibly dug those burrows themselves, and definitely not remove the trees’ roots. Did they settle in abandoned burrows dug out by rabbits, foxes or badgers?
- Fluffies are scared of the dark. Would a fluffy really want to settle underground?
- What part of their DNA would allow for a burrowing behaviour? Horses don’t dig burrows (afaik). Maybe hamster or rabbit DNA?
(Not critizising the artwork here, it’s cute. Just wondering…)
