Airstrip

There are two versions of Delfino Airstrip, the version you start out in at the beginning of the game, and one that you can return to later in the game only after completing all Shadow Mario levels.

First Airstrip
After hitting "Start" on file select, a 70 second cutscene plays. After this cutscene, there is a single text box with Peach before you gain control of Mario. The goal here is to get to the loading zone for the next cutscene as quickly as possible. The loading zone is a small cylinder centered around Fludd. It does not matter if you pick up fludd as you enter the loading zone, it is the same speed either way. You do not have to be touching the ground to start the cutscene, but you do need to be low to the ground to be in the loading zone.

After this 80 second cutscene, you must defeat the polluted piranha plant to spawn the shine. It is woken up after being sprayed for about 2 to 3 seconds. You should get close to it while spraying, so you can spray it as soon as possible after it wakes up. Once it does wake up, mash R and A to spam spray so you can spray it as soon as the small cutscene finishes. With this plant, you do not have to wait and time your sprays like the others. It will not delay if you spray it while its mouth is closed, so you can just shoot a steady stream at where its mouth will be when it opens.

After spraying it three times, its death animation will play, after which the shine will spawn. You should position yourself in a way that will allow you to collect the shine quickly once it spawns. You can do this by lining up with your back toward the plant, then when steam starts appearing, you can hold R down all the way then hit A to do a backflip. You need the spray nozzle equipped to do this. If you lined it up correctly, Mario will land in the right place as the cutscene starts playing. After the shine spawn animation finishes, hit A and then L immediately after to do a short ground pound and collect the shine.

Second Airstrip
Going back to airstrip again becomes available after the flood in Delfino Plaza, which happens when episode 7 of every Area has been completed. To get to airstrip, you need to pay 10 coins to the dancing Pianta near Ricco Harbor in the Plaza. The 10 coins can be quickly collected in the sewer between the entrance to Corona Mountain and Box Game, Alternatively, you can collect 9 coins from the sewer between the Pinna Park cannon and the roof near Ricco Harbor, and the tenth coin from either the box on the roof or the sign next to the Pinna Park cannon.

This second visit to airstrip is considered a part of Delfino Plaza. This means that any coins collected in Delfino Plaza will be carried over to Airstrip, and vice versa. The blue coin in Airstrip counts toward your Delfino Plaza blue coin count on the Z-menu, and the Plaza and Airstrip share a 100 coin shine.

The categories that visit Airstrip a second time are 96 shines and 120 shines. In both these categories, you need to collect 99 coins, and the red coin shine. If you collect 100 coins in this level, you can spawn the Delfino 100 coin shine here along with the red coin shine. However, you can only collect one of these shines before being taken back to Delfino Plaza. So it is best to wait and get the 100th coin in Delfino Plaza so you can collect the 100 coin shine there. If you do accidentally collect 100 coins, you should go ahead and collect the red coin shine. You can spend one of your coins on the chuckster in the Plaza, and collect the 100th coin again in Delfino after getting the chuckster shine.

(Note: The only difference in this level between these two categories is that you do not collect the blue coin in the ice cube in 96 shines)
