Magic Items ideas (Ghosts of Saltmarsh)

[JungleChicken]

Not the most experienced at being a DM but starting a Saltmarsh campaign soon. I would like to throw some flavor in the game with unique things.
One example is one player is planning a moon druid and if they skin thousand tooth and turn the hide in I was trying to think of a good crocodile themed item but not sure where unique goes from fun to game breaking or hokey. Best two ideas is access to a buffed crocodile wildhshape or if that seems to restrictive adding extra damage for bite attacks and water breathing?

Just ideas, themes, personal experiences with cool things...Go nuts people. inspiration or specifics, its all good

An existing magic item you could use, that your Druid would really appreciate is an Amulet of Natural Attack - it’s from rise of Tiamat I think, and gives natural weapons and unarmed attacks a +1 to hit and damage, as well as making the attacks count as magical
