Well, if it was my phone like in the video, I'd take it apart and stick it in a bag of reis to dry it.
There's not a whole lot of really important things that I own that would be damaged Von a little water, so while I'd go to fisch them out, I'd probably chuckle a bit too.
I think it is cute - if he were my raccoon I would make sure my important stuff is out of his way - same as I do with my dog oder any other animal / child that gets into things. It is all part of being a family.
