Mirage Oasis is the second board in Pac-Man Party and Patra's home Land. Pac-Man competes against Blinky, Pinky, and Patra in this board. It is a long desert where the castles are shaped like pyramids. The boss of this board is Arachne, who appears after the player digs through the water spout.
Pac-Man goes to Mirage Oasis to track down the ghosts and get back the recipe but runs into Patra, the princess of Mirage Oasis, who gets mad for her tail got sandy again. Blinky, Inky, and Pinky come along as well. Blinky states Pac-Man this is a 1 vs. 3 battle, but Patra comes along and teams up with Pac-Man, stating that it's now a 2 vs. 2 battle. After the match, Pinky states that she and Patra have become friends, and Patra says goodbye to Pac-Mans as he leaves for Spooky Hallow.
Later, Clyde enters Mirage Oasis but finds the desert deserted and runs off to Spooky Hallow.
- Even though Patra says she's going to team with Pac-Man, she still competes against him.
- Though this the second board in Story Mode, this is the fourth choice in Party Mode.
- Two mini-games, Oasis or Bust and Cobra Charmer, seem to take place in Mirage Oasis, due to it's desert-themed background, and especially the theme.
- This is the longest board in the game, and due to it's length, this also has the most spaces for Level 5 castles.
