Mole rat repellent

Mole Rat Repellent is a special green chemical concocted up by Moira Brown of Megaton to try and well....repel mole rats away from the user. It is given to the player (conveniently placed onto a wooden stick) to smack numerous mole rats for testing to put into her Wasteland Survival Guide. Upon testing it though the discovery is made that instead of simply repelling the affected rat...it actually will cause their head to explode in a cloud of blood and gore.
