Navigating to parallel universes at all is nearly impossible for a normal player to manipulate the exact speed, positioning, and angles needed to skip the moat door is all but impossible without tool assistance. It's technically possible to beat the game with only one of the two keys (meaning you can skip "Bowser in the Dark World"), but it requires using a "Parallel Universe" glitch on the castle grounds to get into the basement.The "zero-star run" is possible if the player performs a perfect SBLJ, building up enough speed to shoot past even the loading zone for Dire, Dire Docks and enter Bowser in the Fire Sea directly.You still need one star to bypass Dire, Dire Docks, though. By doing a BLJ on the small staircase near that door at a very precise angle and position, you can build up enough speed to clip through the door without using MIPS. The "one-star run" has the player bypass the 30-star door with a different glitch: the Side Backwards Long Jump (SBLJ), which is one of the most difficult tricks to execute in all of Mario 64.

You then need to collect one more star to bypass Dire, Dire Docks and clear Fire Sea, before going upstairs and using two Backwards Long Jumps (one on the 50-star door, then on the Endless Staircase) to reach "Bowser in the Sky."
