This is Draggadon who has appeared in Captain Toad: Treasure Tracker and Paper Mario: Color Splash. He usually flies around and attempts to breathe down fire, prepare a dash attack, summon meteors and enemies. There are configs to how he is harmed in which allows him to be harmed from his body or not. If that is disabled, then you can also hurt him by throwing certain npcs at his mouth whenever he charges a giant flare attack. There are tons of configs of how he can be fought and behave. He'll be in my next Boss Army Pack update in the future: https://www.smbxgame.com/forums/viewt...

NPCs used from this footage are made from MegaDood, Deltom, and S_Koopa0 (not shown but it's the Volcano Debris from NSMB series)
