Hotel Mario: Missing/Scrapped 6th Hotel Cutscene

So i saw a mistake in the beta build of Hotel Mario. it goes like this: After completing Ludwig's hotel in the final build, the background for the cutscene doesn't even change. And in the beta, when Luigi says "Look! She's going to Wendy's hotel!" the plumbers' colors are messed up. so if I had to guess, there's a scrapped version of the cutscene after Ludwig's hotel is destroyed. Maybe this video i made might be the one because I saw a leaked hotel that includes an underwater-themed palace level. in a 6th hotel cutscene where you find a scuba mask thingy power-up (Hotel has those cutscenes that cause stuff to the 7 hotels), they have more stamina when equipping it. Then an Iggy fight starts, and another cutscene starts where Mario & Luigi rescued the princess and reached the grassy surface again. But she got teleported or taken (by Wendy's Pennies) to Wendy's hotel. So yeah. that's the whole 6th hotel theory.
