What do i do with sea cucumbers

I know they don't give any xp, but are they sellable? I have checked Willy with no luck.

 

you can ship them, but i would keep them cause they are one of the ingredient to make Lucky lunch, which gives +3 luck for around 10mins... I use it before bulldozing mine/skull cave for better loot lol

 

Ask Haley for some ideas, only if you're a girl though (and you should already know what it's for).

 

Also perhaps just keep them lying around. I've had Willy give me so many Help Wanted "keep fishing alive" quests and 3 Sea Cucumbers were one of the things he asked for.

 

Willy also likes receiving Sea Cucumbers as gifts to build up his friendship level.
