So I've been trying to work on the crab-cannon arm, but it's definitely a struggle as I'm not that good with mechanical things. I tried to incorporate some of the water guns ideas I have in my reference board, but it's hard
That's the sketch I have so far. He's gonna have a big water tank on his back which connects to the arm, and then there's smaller water reservoirs on the claw itself. At least that's what I have in mind.
