Sky Kid/Stage elements

Mission Targets
In every mission, there is one particular target that you will attempt to bomb in order to earn a 10,000 point successful mission bonus. There may, however, be other targets along the way that you can also earn bonus points by destroying. When you strike a target with a bomb, you will earn 1000 points if you hit it directly in the center and demolish the entire target. If you only hit the left wing or the right, you will earn 500 points instead, and you will not earn a bonus for that target at the end of the mission. The Air Successor is the final enemy. It makes a brief appearance in Mission 11, and appears in the final showdown at the end of Mission 21.

Billboards
Through certain missions in Sky Kid, you will fly over different billboards. Some billboards are just for show, while other billboards have a special property. If you perform a loop over these special billboards, one of two items will appear. If a good item appears, you can collect it for 1000 points. But if a bad item appears, avoid it or it will cause you to crash.

Special signs
Perform a loop while flying over these signs to make a bonus or penalty symbol appear on top of the sign.

Hidden Bonuses
There are three types of hidden bonuses. They must be shot in order to be revealed and collect, so you must know the exact location to fire upon. The arcade mission walkthrough will reveal their location. These bonuses are not present in the NES version.

Changeable objects
There are a handful of objects which change in appearance when you fly past them, perform a loop on them, or shoot at them.
