Insights

Limited to a short retail window, the Dry Bowser Castle Battle Expansion Set (2023) centers on exclusive Dry Bowser and variant characters and has display appeal that supports measured upside, and dependence on an electronic starter plus franchise refreshes creates notable volatility and remake risk.

“This set is the first to feature Dry Bowser, debuting the villain in the world of LEGO Super Mario. Otherwise, it includes a Bone Piranha Plant, Bone Goomba, a Magmaargh and a Purple Toad. As with all expansions, an interactive figure is not included so you’ll need one of... More the three starter courses to play.”

Full review at www.brickfanatics.com

“Dry Bowser Castle Battle (71423), seems to be another expansion set that ties up with previous LEGO Super Mario sets in terms of functionality and course features. We even get to see a similar Purple Toad found in LEGO Super Mario Character Packs Series 5 (71410), a Bone... More Goomba from LEGO Super Mario Character Packs Series 2 (71386), and a new Bone Piranha Plant and Lava Blargg build as well. I also love the aesthetics of the castle’s chain while giving it the same vibe as that of Bowser’s Castle Boss Battle (71369).”
