Super Soaker Attachments

My pals came on Sunday (after I'd said NO! because I had a machinima job I had to ring them up and say COME! when I didn't get the nda in time). Mrs. Pal showed me her implanted catheter, which I'd wondered about as it can stick out anywhere (it's low in the abdomen on her though). It's not a red tube anymore - flesh-tinted and a foot long like a scrawny penis (as C said). I told her she should get a super-soaker attachment for it, in case someone gives her trouble. I can just imagine it :-D If such a thing doesn't exist I don't know why.

Writing in the snow is also a possibility.

Update:
E: I think the catheter super-soaker is great, tho I doubt she would be able to build up enough pressure to make it spectacular!
O: No - the gizmo makes the pressure. Right now she has to empty her bag all the time, but with a Super Soaker attatchment she could target shoot for fun!
