Jet Airship is the 2nd level of Koopa Planet. It is unlocked via completing 8-1: Batallion Frontier and finishing that will unlock 8-3: Burnstone Flowfalls. It is an autoscrolling airship level, without a boss. It has a vast supply of Rocket Engines which support the fact that this level scrolls rather very fast. Hitting all of the switches in the four Switch Palaces makes this level much easier.
- After the 1st 3 Doughnut Blocks, run into the area, then briefly wall-jump to reach it.
- In the next area, find the army of Rocky Wrenches, then find the coin by briefly performing wall-jumps before it's pushed offscreen.
- Just before the flagpole, find the coin in a small alcove.
