There was a tornado heading towards a village. Aang, Katara, and Toph went out to the village to stop the tornado. And what were you and Sokka doing? Babysitting Momo. You two didn't have any bending powers, so you wouldn't really be any help with the tornado. It sucked, though.

Momo was on Sokka's shoulder, who was looking disappointed. "Man, I can't believe we have to sit here and babysit while the others save a village."
