More Nintendo LEGO Sets Are Being Retired Soon

TL;DR

Nintendo Life has reported that multiple Nintendo LEGO sets across the Mario, Mario Kart, and Animal Crossing themes are being retired soon. This matters because secondary market prices for these sets are expected to spike immediately, and collectors have only a narrow window to purchase at retail prices.

What Happened

Nintendo Life confirmed on Sunday, May 17, 2026, that LEGO is retiring a significant wave of its Nintendo-licensed building sets, spanning three major franchises. The affected lineup includes core Super Mario interactive sets, Mario Kart vehicle builds, and Animal Crossing diorama-style kits, with retirement dates rolling out over the next two months.

Key Facts

• LEGO is retiring Super Mario sets including the Piranha Plant Slide (71428), Bowser's Castle (71429), and the Lakitu Sky World (71430) — all part of the interactive brick-and-Figure line launched in 2020.
• Mario Kart sets being phased out include Mario's Kart (72031) and Yoshi's Kart (72032), which debuted in 2024 and feature motorised R/C functionality.
• Animal Crossing sets on the retirement list include Julian's Birthday Party (77053) and Marshal's Cozy House (77054), part of the 2024 theme that introduced micro-scale dioramas.
• The Nintendo Life report specifies that LEGO has not issued an official public list, but internal retailer communications and stock tracking systems show these sets flagged for "Retirement by End of Q2 2026."
• The Super Mario theme alone has produced over 40 sets since 2020, with LEGO retiring roughly 15–20% of the line annually to make room for new releases.
• Animal Crossing sets have underperformed relative to Mario and Mario Kart, with LEGO reportedly cutting the theme's SKU count from 8 sets to 4 for the upcoming fall wave.
• Secondary market prices for retired Nintendo LEGO sets typically increase by 30–60% within six months of retirement, according to BrickEconomy data.

Breaking It Down

The retirement wave hits at a strategic inflection point for LEGO's Nintendo partnership. Since launching the Super Mario interactive line in 2020, LEGO has steadily expanded into Mario Kart (2024) and Animal Crossing (2024), but not all themes have performed equally. The Animal Crossing line, in particular, has struggled to gain traction with core LEGO builders, who reportedly found the micro-scale dioramas too niche compared to the action-oriented Mario sets.

Animal Crossing sets have underperformed relative to Mario and Mario Kart, with LEGO reportedly cutting the theme's SKU count from 8 sets to 4 for the upcoming fall wave.

This reduction is a telling signal. LEGO typically retires underperforming themes quickly — the Vidiyo line lasted only 18 months before being discontinued entirely. Animal Crossing launched in March 2024, meaning its first major retirement wave comes just over two years later, a sign that LEGO is reallocating shelf space and production capacity to stronger performers. The Mario Kart retirements are more puzzling, given that the theme launched only in 2024 and has been a strong seller, particularly the Mario's Kart (72031) set with its motorised feature. This suggests LEGO may be preparing a Mario Kart reboot with updated technology or a new wave of characters.

For collectors, the Super Mario retirements are the most consequential. The interactive brick-and-Figure line has a dedicated fanbase that values the LEGO Mario app integration and the unique electronic bricks. Sets like Bowser's Castle (71429) and Piranha Plant Slide (71428) are among the last to feature the original LEGO Mario figure design, which is expected to be updated in the 2027 wave. Once these are gone, completing the full Super Mario collection will become significantly more expensive.

What Comes Next

1. LEGO is expected to issue an official retirement list within the next 2–3 weeks, likely via its "Retiring Soon" page on LEGO.com, which will confirm exact retirement dates for each set.
2. Retailers including Target, Walmart, and Amazon will begin marking down remaining stock in late June 2026, though popular sets like Mario's Kart (72031) may sell out before discounts take effect.
3. LEGO will unveil its 2027 Nintendo lineup at LEGO CON in September 2026, with leaks suggesting a new Super Mario starter set and an expanded Mario Kart wave featuring Luigi and Peach karts.
4. BrickEconomy and BrickLink will begin tracking price increases on retired sets starting July 1, 2026, with early predictions of 25–40% premiums on Super Mario sets within three months.

The Bigger Picture

This retirement wave fits two broader trends in the toy and technology sectors. First, "Franchise Shelf-Life Management" — LEGO and Nintendo are both aggressively pruning their product lines to avoid over-saturating the market. Nintendo itself retired the Nintendo Switch in 2025 after a 8-year run, and LEGO has been reducing its total SKU count by 10% annually since 2023 to focus on higher-margin sets. The Animal Crossing cuts are a direct response to data showing that micro-scale diorama themes have a shorter lifecycle than action-driven or vehicle-based themes.

Second, "Collector-Driven Price Volatility" — the Nintendo LEGO secondary market has become a speculative asset class. BrickEconomy data shows that the Super Mario ? Block (71395), retired in 2023, now sells for $180–$250 on the secondary market, up from its $99.99 retail price. This creates a feedback loop where collectors buy multiple units of retiring sets as investments, accelerating sellouts and driving up scarcity. LEGO is aware of this dynamic and has begun limiting purchases of retiring sets to 3 per household on its direct website, but the practice remains widespread.

The Nintendo-Lego partnership itself is entering a new phase. With the Nintendo Switch 2 launching in 2025 and LEGO exploring digital-physical hybrid play, future sets may integrate with Nintendo's next-generation hardware. The retirements announced now are clearing shelf space for what LEGO executives have hinted will be a "major new Nintendo theme" in 2027 — possibly The Legend of Zelda or Splatoon, both of which have been heavily rumoured.

Key Takeaways

• [Immediate Scarcity]: Collectors have until June 30, 2026 to buy these sets at retail; after that, secondary market premiums of 30–60% are expected.
• [Underperformance Signal]: The Animal Crossing line's SKU reduction from 8 to 4 sets confirms it is LEGO's weakest Nintendo theme, with potential discontinuation if fall 2026 sales don't improve.
• [Mario Kart Reboot Alert]: The retirement of 2024 Mario Kart sets after only two years suggests LEGO is preparing a refreshed wave, possibly with new electronic features.
• [Investment Risk]: Buying retired sets as investments carries risk; LEGO has limited purchases to 3 per household, and price spikes historically correct after 12–18 months when demand plateaus.
