LEGO Super Mario Prince Florian & Castle Bowser 72042 – Epic Boss Battle Building Set

Step into the climactic Super Mario showdown with a brick-by-brick fortress

The LEGO Super Mario Prince Florian and Castle Bowser set (72042) invites game fans aged 9 and up to recreate the finale in a tactile, imaginative way. This expansive 1,251-piece build centers on a massive flying castle equipped with fireball action, a detailed interior, and a stand that can be lifted to simulate dramatic flight. The result is a portable arena for storytelling: kids can stage dramatic rescues, chase sequences, and bold boss-battle moments that blur the line between video game and brick-built adventure. The scale of the castle and the range of movable parts offer a satisfying sense of accomplishment as each section comes together.

• Impressive build and display – A towering fortress with authentic Super Mario styling to spark curiosity and pride in completion.
• Dynamic play features – Lift Castle Bowser off the stand, drop the top to reveal interiors, and fly the castle around the room for action-packed scenes.

The set includes four distinct figures: Pink Yoshi, Fiery Note Piranha, Prince Florian, and Wonder Bowser Jr. Each figure adds to the narrative potential, letting kids stage rallies, rescues, and battles with familiar allies and foes. The interior design includes a cell to trap Prince Florian, inviting suspenseful moments and clever problem-solving as players figure out how to release him or reposition the castle for alternate outcomes. The interactive element is enhanced by the possibility to pair this set with other LEGO Super Mario figures and sets to trigger additional digital reactions when used with compatible bricks from the broader line.

• Interactive play potential – Place compatible LEGO Mario, Luigi, or Peach figures to unlock digital reactions during the final boss battle.
• Expandability – Combine with other LEGO Super Mario sets to create an evolving universe of adventures.

For builders who enjoy guided instruction, the LEGO Super Mario app offers step-by-step digital directions and creative ideas to accompany the physical build. The app-check helps ensure a smooth assembly process, especially for a model of this size. When complete, the castle measures a bold presence on a shelf or in a play space, with each element designed to withstand repeated play sessions and imaginative storytelling without sacrificing detail.

Whether you’re gifting a budding designer or fueling a long-running LEGO session, Prince Florian and Castle Bowser is a vivid, action-forward option. It’s a strong choice for kids who love Super Mario, story-driven play, and the tactile delight of building with bricks.
