As you may know, I'm trying my best to speedrun Dream Team while also getting as much done as possible. My current progress right now is finding the tour guide for Mount pajamaja but I am in the desert trying to see if I could grab some of the pi'illo folk before heading off, this lead me to discovering a few things with the sequence break I did with the desert skip.
First of all, I thought the trigger that changed the room's sequence was being in the room with the dream stone early and entering the main dig site with the Zeekeeper statues, however, it was just being in the room that altered the room's state. That also lead to another sequence break where if you went the intentional path (main dig site to drill areas), you will still be going to a softlock as the last pi'illo you need will not appear and upon triggering the cutscene with the drill boss, they will interact with an invisible pi'illo and lock your game.
I may also add that the room was also in a different state where the blockage that normally stops you from going right of the drill site entry is no longer there. I forgot it entirely when I first lost my save file on first playthrough since I've not played the game in years. Even Starlow said the line that you'll need the drill to catch up with the drill boss.
This was my small discovery with doing the glitches, I'll have to rewind to before I entered the dig site to see if I can do any more out of sequence (also small note, getting the bros attacks in a different area does not result in getting the bros attack in battle, you need the first ones or else you'll be stuck with jumps and hammers as your only attacks. Game made with duct tape and a dream)
