Looking for build suggestions; solo hybrid Sarco, Spino, and Sucho

I've tried to look through posts on here and tiktok, but there always seems to be conflicting suggestions.

I'm a solo player, passive unless attacked, and like to explore, so any build that'd help me defend myself but also be able to swim around would be really appreciated! Tips and play styles get you bonus points for being extra helpful, and a lifetime of my appreciation.
