LINK TO ENEMY EXPLANATION: https://www.mediafire.com/file/wp41soylpxl803s/Stage_1-1_or_Stage_5-3_Some_Enemy_Explanations.txt/file The truck is called Super Mega Ultra Flying Truck #19, and will be a mini-boss like the flying ship in DH1. The crane carrying it attached to Maruyama's ship move up and down, carrying the ship with it. It shouldn't spam attack, since it will probably be in the first level, but if he is used for 5-4, he will attack decently fast. Destroy the crane to knock the truck out of the air (preferably, to its destruction). The birds are called Dummy Pterosaur and can attack by flying towards the player, flying straight, creating whirlwinds, pecking, or attacking with their wings. Further information can be found in the MediaFire link.
Based off the flying ship from DH1. I also did this at an art class (on paper), with the base picture being a regular truck on the land, with supplies like a refrigerator and a microwave.
