Fans love the inclusion of the hammerhead shark and bubble cockpit at a low entry price, though experienced builders find the 4+ build far too simple.

📝 Our Take

Ocean Mini-Submarine is a fantastic entry-level set that brings underwater adventures right to the playroom. With its bubble cockpit, inspection arms, and a fun hammerhead shark figure, it packs plenty of play value into a compact 4+ package.

This set is perfect for younger builders and ocean enthusiasts just starting their LEGO journey. The inclusion of a Starter Brick makes the 45-minute build frustration-free and builds confidence for kids taking their first steps beyond DUPLO.

Skip this if you are an older builder looking for complex techniques or high piece counts. At only 41 pieces, seasoned fans will breeze through this in minutes and find little challenge.

Compared to larger LEGO City Ocean Exploration sets, the Ocean Mini-Submarine offers an accessible entry point at a fraction of the cost. While it lacks the intricate mechanisms and massive vessel builds of sets like the Ocean Exploration Ship (60266), it captures the same aquatic theme perfectly for a younger audience.

1 Minifigure Included
