A/N: Hi! It's been a while since I updated Kataang story lol. Oh well. Don't ask how or why I got this idea. I just did. I've had this in my head for two weeks lol. Ok so here we go. Woot!

Chapter 21

Natural Gasses

The AangGaang were moving as slow as ever to Ba-Sing-Se.

"Hey Aang! Move this thing a little faster!" Zuko shouted.

"It's not a thing!" Aang said.

"Yeah Zuko. This thing is helping you not become bait for your sister." Katara said.

"Yeah, but… I… still… ok fine, can APPA move any faster?" Zuko asked reluctantly.

"Thank you, but… no. He can't" Aang said.

"AAAARRRGGH!!" Zuko screamed as he threw up his arms in distress. "At this rate we're not going to get to Ba-Sing-Se until next Summer!"

"What we need is an engine of some sort." Sokka said rubbing his chin.

"And how would that help Appa?" Katara asked. "You plan to attach it to his stomach?"

"Well I…" Sokka stuttered.

"Wait, we can maximize our firebending to some sort of accelerant." Iroh suggested.

Everyone just stared at Iroh.

"Hey the Fire Nation as the best schools in the world." Iroh said bluntly.

"Well that's a good idea, but people might notice. Also how long could you keep that up? It's still a long ways to Ba-Sing-Se." Sokka asked.

Iroh shrugged. "Just tossing ideas."

"Well we'll keep that one." Sokka said. "But we need one that won't tire us out."

"Just shut up and use Iroh's idea." Katara said.

"Oh just shut your air hol-" bbbbbbbbbbbbpppppppptttttttt. Sokka was interrupted.

"Heh, maybe you should shut yours." Zuko said waving a hand in front of his face.

"Well like you've never had gas." Sokka retaliated.

"Not like-" bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbpppppppppppttttttttt!

"Spirts Zuko. Uuh." Katara yelled holding her nose.

All of the sudden, bbbbbpppppptttttt!!!! Aang went about 10 feet in the air. Again bbbbbppppttttt! This time it was Katara. BBBBBBBBBBBPPPPPPTTTTT!!! The loudest was no Toph.

"That's it I got an idea!" Iroh shouted. He snapped his fingers and a little light came on his fingers. "Hold tight to something." Iroh shouted.

Then out of nowhere BBBBBBBBBBBBBBBBBBBPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!!!!!!!!!!!!!!!!! Iroh stuck his finger next to it and all of the sudden it burst into flame. The bison rocketed at speeds never before seen.

"AAAAAAAAAAAAAAUUUUUUUGGGGHHHHH!!!!!!!!!!" The group screamed as Iroh laughed maniacally still keeping his finger in place.

From the ground the people tracking the Avatar were dumbfounded. It was a strange sight. A group of teens on a flying bison with flames shooting from it, with an old man laughing hysterically.

"Follow them!" A person clad in a black cloak shouted. The group used incredible speed to follow the bison rocket.

Back on the bison Iroh was keeping the fire going. "To Ba-Sing-Se! To Victory!" He shouted over the flames holding a fist in the air. And Gaang sped off.

A/N: Seriously don't ask. My next chappie is going to be more serious lol. It's actually going to be a fight scene! Woot! Haven't had one of those in a while lol. Oh well. Hope you liked this chapter. Cya all soon! I'll try to update sooner!
