Fire will do.
That is one abnormally resilient manjuu. I wonder if anyone can think of a use for something like that (other than as an indestructible stressball).
I think it would be more of a stress increaser, than reliever... it would spend the whole time puffing up and demanding things off you rather than getting hurt.
thats why you break out the sharp pointy stuff.
I think the cries of "WHY ARE YOU DOING THAT !?!?!" while you squeeze it would be entertaining.
I would like to have one of those ... remains for abuse ...
