The LEGO Mario universe has just been further expanded. Joining the original LEGO Super Mario and Luigi starter sets, the Peach starter course and castle expansion set are yet another expansion set featuring none other than the supervillain himself, the Bowser, well, the skeletal version one aka the Dry Bowser. Accompanying flesh-off Bowser is his booty-trap-filled Dry Bowser Castle.

The LEGO Super Mario Dry Bowser Castle Battle Expansion Set (71423), as it is called, uses 1,321 LEGO elements to recreate the Dry Bowser Castle (or at least part of it). The expansion set allows fans to use interactive LEGO Mario, LEGO Luigi, or LEGO Peach to rescue Purple Toad from within the deep, dark depths of the castle. 

“Set in an iconic Super Mario location, fans are tasked to find the secret entrance (just watch out for the Magmaargh!), defeat the Bone Piranha Plant and Bone Goomba, use the crane to rescue the Purple Toad, then quickly grab the key. What lays behind the door is secret – you’ll have to wait and see what’s revealed!”
