Main Chamber Skip
In the Mermalair Main Chamber, there is a bridge that can be lowered by the Mermalair Computer's master button. There is a gate guarding the master button, which can be opened by pressing 4 buttons spread throughout the entire level. The bridge allows the player to access the loading prompt to enter the Villain Containment System.
The loading prompt is active all the time, even when the bridge is not lowered. At the Spinning Towers of Power, Patrick is able to use the slide to build momentum and jump straight to the loading prompt.
By walking into the corner of the slide, Patrick enters his sliding state and begins to build momentum. After a few seconds, the player can jump from the edge of the slide with great speed, and reach the Villain Containment System's loading prompt.
