Sokka, this worked in the lake and I have no idea if it'll work in an ocean, but humor me- for fishing, would a powerful jolt of electricity or a magnetic field help you for catching things. If it does, Linda and I can help, if it doesn't, then that's fine.

[He's followed the rest of this thread so he has a fairly good idea what's going down and... he remembers when him and Linda messed up shallow fish using her abilities. He might as well see if it's applicable for the ocean]
