"We can do that!" Eins exclaimed, looking over the sleeping spirits. "Three heads for three kids! Not a problem!"
"Don't get ahead of yourself, Eins," commanded Zwei. "We may be a guard dog, but we're still quite busy."
"Shouldn't it be easy then?" asked Drei. "If we have three heads, can't one of us watch them while the other two rest? Isn't that what we do with the prisoners?"
"Yeah! Listen to him, Zwei! He has a point!"
"No."
"Why not?"
"Come ONNN, it'll be easy!"
"If it'll shut you two up, fine. You have no need to pay us." Eins and Drei cheered in unison at Zwei's giving in. Finally--they'd be able to do what they do best for someone else.
"We're going to need someone who is capable of watching over a bizarre disease alien and a troublesome space demon. Any help is greatly appreciated, and you will be paid generously. Be warned, however. This is not for the faint of heart, the germophobic, or the weak. Come prepared with a generous helping of sweets, food, and heavy artillery."
