Appa was swimming in a river but it was polluted. Aang hops on Appa's saddle and was dirty.
Aang: Hey, guys, I think this river's polluted.
Sokka: So that explains why me and Sako can't catch a fish around here. Because normally my fishing skills are...off the hook.
Sako: (Chuckle)
Katara, Aang, Ty'lee and Aang slowly look at him and he stops laughing.
Toph: Too bad your skills aren't on the hook.
The five laugh at Toph's joke.
Katara: It looks like we'll need to go somewhere else to get food. Assuming that'll fit into Sokka's master schedule.
Sokka looks at his scedule.
Sokka: Hm....it's doable. But that means only two potty breaks today.
Aang looks over at a small village.
Aang: Hey, maybe we can get food there.
After a while they make it to some land and Aang covers Appa.
Aang: Now you look just like a little hill with horns. Bye buddy.
Aang walks off as Sako pets Appa.
Sako: I'll get you something good.
Appa: (Low growl)
The group walks over and looks down at the town.
Toph: I don't feel anything. Where's this village?
Sokka: It's in the middle of the river.
Man: Sure is. My name is Dock. Mind if I ask who you are?
Katara: We're um, from the earth Kingdom colonies.
Dock: Wow, colonials. Hop on, I'll give you a ride into town.
Sako crouches down and Toph hops on. Ty'lee saw this and pouts. Sako looks at her.
Sako: Hm?
Ty'lee: Next time I want back rides.
Sako: -_-(Sigh) Fine.
She giggles. Katara, Aang and Sokka laugh as Sako gave them a look shutting them up. They got on the boat.
Katara: Why do you guys live on the river?
Dock: Because we're a fishing town. Dock points at a fire nation factory.
Dock: At least that's how it was before the factory moved in. Army makes their metal there. Moved in a few years ago and started gunking up our river. Now our little village is struggling to survive.
The group makes it to the village.
Aang: Thanks for the ride.
They looked around to see the people sad or sick.
Katara: Look at this place. It's so sad.
Ty'lee: We have to do something to help.
Sokka: No, Ty'lee we can't waste our time here. We have a bigger mission that we need to stay focused on. These people are on their own.
Katara walked over to Sokka.
Katara: These people are starving, but you turn your back on them? How can you be so cold and heartless?
Sokka: I'm not turning my back, I'm just being realistic. We can't go around helping every rinky-dink town we wander into. We'll be helping them all by taking out the fire lord.
