A freeloader Rex crashing at a friend's place gets a random package delivered to him, containing a pool toy. However, upon giving into his fetish urges and inflating such a thing, he discovers that it turns those who touch it into a much more Vinyl* form. (*Vinyl being the material that a pool toy is made out of. Kinda like Latex.) How will this Rex explain such a thing to his friend? And what possible things will he end up trying in his new form?
