Spliced!

Entrèe becomes obsessed with getting everyone to like him. An accident with a pair of very tight jeans makes him realise that the milk from his top-right udder, "Nugget", is very tasty. Everyone loves the "Nugget" milk, and Entrèe soon becomes incredibly popular, to the point where he shuns Peri. However, everyone else then becomes addicted to the milk, and when "Nugget" runs dry, they chase after Entrèe.
