Can Cow Come out & Play?/Horn Envy

The Red Guy is depressed because no one will play with him. After seeing Cow has Crabs the Warthog, he wants to play with her because he has Crabs's doll house. When he askes to play with Cow, she tells him not if he was the last man on earth. With that he locks the entire world in a trailer, and is the last man standing: but Cow still won't play with him.
