Get a status guard, which gives you status-defx4 ability. Cerberus has a status-defx4 ability as well. Then junction 100X Pain, Confuse, Berserk, and sleep (I think) to Status defense. As well, as already mentioned, have Siren's treatment command junctioned to the person with Status-defX4, and keep mugging until you get one.

Or you could just forget about mugging, junction 100X Firaga to elem-atk-j, and kick the crap out of 'em. As long as you have the right junctioning to status defx4, you'll be able to survive bad breath. I think one victory will get you four, if not a few tentacles.

Or you could card the Marlboro, which gets you the tentacles, as well as a Marlboro card.
