Mario & Luigi: Dream Team

Mario & Luigi: Dream Team is the fourth installment in the Mario & Luigi RPG series. This time, Mario and company are invited to Pi'illo Island by Dr. Snoozemore, the island's leader and resident sleep scientist/Pi'illo historian. The focus of this game is using Luigi's dreams to access the dream world and saving the trapped Pi'illos from the Dark Stone's nightmare chunks and stopping the bat king Antasma and Bowser from using the Dream Stone to take over the world (and kidnapping the Princess).

Revisional Differences
A downloadable update was made available on September 3rd, updating the game to Version 1.1, similar to Mario Kart 7's downloadable update.

Along with adding a "Version 1.1" graphic to the top-right of the title screen, this update fixed several major bugs:
 * In one segment of the first Mount Pajamaja tour, the Mario Bros. would have to spin jump into the Massif Bros. to clear fields of icicles obstructing their path. A major oversight in the original release was that if the player were to take certain actions during this point, they would inadvertently prevent themselves from progressing by leaving the required path obstructed.
 * In the original release, the game had a tendency to freeze repeatedly at inconvenient times, especially in Somnom Woods and Neo Bowser Castle.
 * In the original release, a bug was present that prevented Mario from defeating Antasma in Neo Bowser Castle. It is never specified what this bug is, yet it can be assumed that either the game doesn't recognize that Antasma was defeated, or that the game would freeze at a certain point in the battle.
 * In the original release, when fighting Antasma X in the Battle Ring, the game had a chance of freezing when Dreamy Luigi is freed from an Antasmunchie X.

Starlow?
When exiting the Battle Ring, shortly after Dreambert exits to...wherever it is he goes, the screen briefly blinks and Starlow's twinkle sound can be heard. Nothing else happens, and you gain full control of Mario and Luigi immediately afterward. It's likely this is just the game checking if the Zeekeeper's Feathers were just collected from battling Grobot X, and attempting to play the brief cutscene afterward.

After the Feathers are collected, there's no need to redo the cutscene when exiting the Battle Ring, so the action stops midway, causing the screen flash and twinkle sound effect.
