Great selection of Heroes this time around. I'm going to jump in with Tide, update the cannon i have and base a set around it. I'm thinking, netting, rope, old glass fishing floats, fish, shells, scales etc etc.
I really wish morphling's budget is a bit higher, especially the misc slot. I was going to make water serpent/snake pet swirling around his body up to his head and a pair of fish wings but there is no way to fit it in :(
