D&D 5E player wants to use fishing pole as his tool proficiency, what can I do with this?

[Kobold Stew]

add proficiency to Constitution checks for sitting around doing nothing.

add proficiency for Charisma (Deception) checks for getting out of routine tasks my wife wants done around the house

add proficiency for Charisma (Deception) checks for self-aggrandizing stories no one is really interested in

The punners better clam up before a mod comes in here & kicks somebody's wrasse.

Yes. If too many people carp about the puns, we'll have to do something about it.

I'd allow the occasional creative use of the skill when dungeoneering - for instance, to hook onto and retrieve a small item from the other side of a crevasse or a trap-filled room, or to lure away monsters by dangling a tasty treat in front of them.

Be careful with the punning - I knew a group once whose dungeon master laid on the fish puns so excessively that his own players bodily picked him up and threw him out of the house.

It was a true case of Carpe DM.

• Or the contest itself could be a facade for something much more nefarious. Maybe the winner of the annual contest is "sent on to a life of luxury and fishing-fame, never to return", and their are always these news postings about how these people are world famous and living large. But in reality, it is run by a cult who sacrifices the winner to a great nasty (which could vary based on party level); and the cult just keeps up a facade to maintain a supply of sacrifices.

AKA "The Running Man."

In my games his 'tool' would be "Fisherman". He gets a bonus to anything that being a fisherman would help with e.g. Weather watching, rowing, identifying marine animals/monsters, area knowledge of estuaries, mending nets etc.

Or this one.
