Limestone Core Wolf - New Ref

Yoooooo this pup looks right awesome now~! His chest looks like a smooth kind of bumpy going down XD
Tho I do have some questions so i understand him better. With his tail, is that water around it since hes a water type Core wolf?
And those antler things on his head, are they symmetrical or nah and what is the material? It reminds me of driftwood twigs but i could be wrong in assuming so i thought I'd double check XD
