The stage consists of four Platforms and two stalactite-like platforms, as well as two Clouds and a Propeller. The four flat platforms are to either side of the top half of the stage, each holding a Balloon Bird. The two stalactite-like platforms are just above the water, and also hold Balloon Birds. Overall, the platforms form a sort of "V" shape. At the top-middle of the stage, there is a Propeller, and the two clouds are above the spawning islands. The two highest Balloon Birds are yellow, the two middle ones are green, and the lowest two are pink.
The stage is perfectly symmetrical with the exception of the Propeller, and it is set up in such a way that two players could take out every enemy before any of them take off fairly easily.
After Phase 12, the phase will be looped just like the other phases from 4 to 12. When looped, the phase will reappear at phases 17, 26, 35, 44, 53, 62, 71, 80, 89, 98, A7, B6, C5, D4, E3, F2, G1, H0, H9, I8, J7, K6, L5, M4, N3, O2, P1, and so on.
