That woudl be fun, I am all for it. Like many others, Peter had not so great months/missions lately so this one could be good for team building/cr strengthening and to have fun.

Thanks! The pic isn't finished but he will look like this.

I'd say he will have little trouble. It's not the same of course, but he is he's used to flying with his jet boots and to the no gravity of space, so it wont' be that much of a change for him. And apparently, Manta rays can swim pretty fast when they put their mind to it.

If there's anything specific you'd like to do or try with Kakashi, just let me know.
