- The Mystery Dimension is hidden in a secluded section on Vorton. To access it you must approach the Jurassic World gateway and then walk towards the screen until you see the gateway on the left.
- The Mystery Dimension is the only portal in Vorton that doesn't require a character Keys, meaning it can be accessed by any character upon collecting 20 Gold Bricks.
- The gateway is made of gold bricks which may be a reference to the golden doors that had to be built by collecting gold bricks in previous LEGO games.
- After the release of the Year 2 content it was discovered that you could play as any character as well as summoning a few gadgets like the Scooby Snack while within the Mystery Dimension. In order to do this you needed to select a character with building instructions like Batman and then leave the instructions menu and a screen appears similar to other LEGO games that lets you select any available character. This glitch was patched in the next update.
