K. Rool Defeated, No End Sequence
This trick is only possible on VC because it uses K. Rool Early.
Prepare a flashback warp to Castle lobby or Castle main, then go back to the main menu. MMM into a file that has only done Funky Weapons Glitch and visited Cranky in training grounds. Complete barrel barrel to get to Castle, then enter Troff 'n' Scoff from the tunnel or the crypt. Navigate past the void zones into the boss door to warp to K. Rool. After defeating K. Rool, Chunky will spawn in front of training grounds, which triggers the Isles escape cutscene and cancels the K. Rool defeated cutscene.
If you use Caves warp before this setup, you can buy Lanky's instrument to skip doing MMM later. You can then free kongs and buy the remaining moves in Castle without causing a flashback warp since Cranky and most T&S portals aren't in a submap.
This trick requires K. Rool Early because if you ever visit K. Lumsy, the Isles escape cutscene will play: • K. Lumsy fails to open Jungle Japes Lobby
This was technically already possible because Caves warp can be used in conjunction with one flashback warp to Isles, so followup flashback warps aren't actually needed.
