Transportaion in Avatar the Last Airbender

I am a big fan of Avatar the Last Airbender so I decided to look at its transportation methods. These are some methods that I found interesting

Appa

Air bender glider

Earth bender glider - Teo

Water tribe snowmobile 

Waterbending-powered submarine

Omashu delivery system

Fire Nation water hot balloon

Earth bending-powered tank

Fire Nation's airship

Fire Nation's gondola

Shirshu - An animal species - Name: Naila

Dragons

Now what?

 I like Omashu delivery system but I might start to do some random sketches then decide. I probably need to watch some episodes to get more pictures and the atmosphere of them.
