The Dark Star was a sentient, evil orb in the game Mario & Luigi: Bowser's Inside Story. It was a rather large blue orb, with a black star with glowing red eyes on the front. The toads dug up the dark star while building Toadtown, wakening it from a deep sleep. The dark star went on to terrorize the world, until it was finally defeated by the Star Sprites. The Star Sprites then sealed the dark star beneath Toadtown in a seal that could only be broken by Princess Peach.
