Playing with rabbitrays totally counts as researching them, probably. I'd be totally up for the two of them doing more of that/maybe trying to actually get poison out of them without hurting them when they remember to do actual work.

And I'd be up for underwater combat maneuvers, too, of course! I'll have to see if it'll be something multiple people are interested in but I might make a post for it if they are (and if not we could do something in an inbox?).
