Super Mario Bros Wonder introduces Castle Bowser as a formidable flying fortress, and this 1,251-piece set brings that memorable boss battle to life. The centrepiece is a large buildable Castle Bowser figure that can be lifted off its stand to reveal an interior prison cell where Prince Florian is held captive.

The set includes five Nintendo characters: Castle Bowser, Pink Yoshi, Fiery Note Piranha, Prince Florian, and Wonder Bowser Jr. Castle Bowser features movable parts that allow builders to simulate the character's flying abilities - the entire castle or just the upper section can be lifted from the base for dynamic play scenarios.

Interactive Features

When combined with LEGO Mario, Luigi, or Peach figures (sold separately), the set triggers digital reactions and enables players to recreate the final boss battle sequence from Super Mario Bros Wonder. The castle's interior design includes specific play features like the character prison and fireball-shooting mechanisms that mirror the video game experience.

Build Specifications

The completed Castle Bowser model measures 31 cm high, 21 cm wide, and 22 cm deep. Designed for ages 9 and up, this set works as both a display piece and active playset. Interactive digital features require one of the separately sold starter sets (71439, 71440, 71441, or 72043) that include the electronic character figures.
