@Ita So like the Event dungeons from Infinite Competitive Dungeon Society? If you don't clear them quickly enough, they turn into field dungeons, imposing the dungeon fully upon the world and altering terrian completey to match what the Event dungeon looked like.

@RebornSauce No, while he didn't enter gear fourth Bounce-man form, it was defintely a gear fourth attack. You can see his arm compressing just like with the normal Kong Gun. Maybe it's something he became able to do after he awakened Gear fifth?
