Super Mario Bros.: The Lost Levels

Super Mario Bros.: The Lost Levels was the second kidnapping of Princess Peach by the Koopa Troop.

History
"This title is the story of Mario and Luigi's new adventures set in the parallel world of Super Mario Bros. The Mushroom Kingdom has been attacked by the clan of the giant turtle Bowser. Only Princess Peach, the princess of the Mushroom Kingdom, can restore the Mushroom Clan, which has been turned into rocks and bricks by magical powers. Now in the hands of the Great Demon King Bowser, Mario must stand up to rescue her and bring the Mushroom Kingdom back to life."

- Japanese Virtual Console

The Koopa Troop returned with a near-identical plan to their first one; take over the Mushroom Kingdom, pull a magic spell to turn all of the Toads into rocks and bricks, and kidnap Princess Toad who is the only person capable of undoing the spell.

The key difference to his plan is to bring Peach to a parallel world, one that is under tighter control by the Koopa Troop. Mario, once again spurred by his desire to free the Mushroom Kingdom, set off into the parallel world.

Traveling through the 8 worlds of the parallel world, defeating the Fake Bowsers freeing the Toads at the end of each castle, Mario reached World 8 and defeated the real Bowser, saving Princess Peach. But just when Mario had saved Peach, she is kidnapped again. Journeying through 5 more worlds, Mario reached Peach, finally saving her and freeing the Mushroom Kingdom from Bowser's control.

All of the Toads were likely returned to their original form via Peach's magic after this event.

Timeline

 * Likely a direct sequel to Super Mario Bros., as Bowser has a near-identical plan in this game to the last one, with the key difference being that he takes Princess Peach to a parallel world.
