LEGO Super Mario Kart Baby Mario vs. Baby Luigi Set (72034) Deal

The 321-piece LEGO Mario Kart Baby Mario vs. Baby Luigi set is down to $23.95 — here's who it's actually right for and what to know before buying.

What you're actually getting for $24

Set 72034 is one of the smaller expansion packs in the LEGO Super Mario line, built around the Mario Kart theme with Baby Mario and Baby Luigi kart figures. At 321 pieces and roughly $23.95, the price-per-piece math lands around 7.5 cents — which is solid for a licensed LEGO set. The build itself is compact, featuring kart racers and a short course segment. It's not a showpiece centerpiece set, but for the price it's a genuinely fun afternoon build for kids around 6 and up, or a lower-commitment gift for a Nintendo-loving household.

The thing worth knowing before you order

This is an expansion pack, not a standalone experience. The interactive features — where LEGO Mario or Luigi figures scan tiles and react with sounds — only work if someone already owns a LEGO Super Mario Starter Course with the Bluetooth figure. If you're buying this cold for a kid who doesn't have one, they'll get a fine building set but miss the app-connected gameplay that defines the line. That's not a dealbreaker, just worth knowing. If they're already in the ecosystem, $23.95 for a Mario Kart-themed add-on with two Baby characters is a reasonable pickup, especially with free shipping factored in.
