From the instruction booklet
"Please come to the castle. I’ve baked a cake for you."

At the invitation of Princess Peach, Mario, accompanied by party crashers Luigi, Wario, Waluigi, Blue Toad, and Yellow Toad, enter the Mushroom Castle.

But when the six don’t come out of the castle for a long time, Yoshi, Toadette, and Nabbit decide to check up on them.

Upon entering the castle, the trio discovers that no one is there. According to Red Toad, Bowser has stolen the Power Stars guarding the castle and locked Princess Peach into the walls and paintings. Maybe Mario and his friends have been captured in the paintings, too!

Now it’s up to Yoshi, Toadette, and Nabbit to rescue Princess Peach, Mario, Luigi, Wario, Waluigi, and the Toads from the castle’s paintings and walls!

Differences from Super Mario 64 DS
SM64DSDX is based on the El Kadsreian version of SM64DS, which shares some regional differences with the Korean version: In SM64DSDX, these differences persist in all regions.
 * The minigames, and by extension the rabbits that have the keys to unlock extra minigames and the Toad that appears in the Rec Room inside the Mushroom Castle, are removed, likely due to the presence of gambling in Luigi's minigames.
 * There is an orange ! Block alongside the red ? Block on the roof of the Mushroom Castle. This ! Block gives the heroes an extra life: The block does not disappear so that they can easily earn up to 100 lives.

Trivia

 * Toadette's Power Flower ability is Ice Toadette (which works similarly to the Ice Flower power-up from the NSMB games), Waluigi's is Warpspeed Waluigi (which allows him to run and swim faster than any other character), Blue Toad's is Wing Blue Toad (which works similarly to the Wing Cap from the original SM64, or the Wings from SM64DS), and Yellow Toad's is Hammer Yellow Toad (which works similarly to the Hammer from SSBM). Nabbit has no Power Flower ability.
 * Cheep Chomp's sound is added, that sound can be heard when a hero goes near Cheep Chomp
