Underwater Loop

The Underwater Loop is a vibrant and playful addition to the LEGO Friends amusement park lineup.

🏆 Best For: Ideal for children aged 7+ who enjoy the LEGO Friends theme and amusement park rides. ⏱ 2 hr build 🧩 389 pcs 🎂 Ages 7+
★★★☆☆ 3.8

Fans appreciate the bright colors and fun spinning action of the Underwater Loop, but some find the build repetitive and the overall design somewhat simplistic. The minifigures are a plus, but the set may not appeal to older builders seeking a more challenging experience.

📝 Our Take

The Underwater Loop is a vibrant and playful addition to the LEGO Friends amusement park lineup. With its bright colors and spinning action, it captures the fun of a fairground ride in LEGO form.

This set is perfect for younger LEGO fans and those who enjoy the Friends theme. The build is relatively straightforward, making it a great introduction to more complex LEGO models. The play features also add to the enjoyment.

Skip this if you're looking for a challenging build or a highly detailed display piece. Consider larger Creator Expert sets for more intricate designs and advanced building techniques.

📈 Investment Analysis

→ Price stable
C+
Investment Grade
⏳ Active
The Underwater Loop, being a retired LEGO Friends set, has a moderate investment potential. While the Friends theme is consistently popular, this particular set isn't exceptionally rare or sought after. However, its relatively low MSRP and decent piece count may lead to gradual appreciation over time, especially if kept in mint condition. The presence of unique elements and minifigures could also contribute to its value. As with any LEGO investment, market trends and collector demand will ultimately determine its long-term performance.

📖 About This Set

Let your child experience the fun of the fair with the LEGO® Friends 41337 Underwater Loop. Realistic features, such as the kiosk where tickets can be bought with bill or coin elements, help recreate the atmosphere of the amusement park. By twisting the function knob children will love watching the chairs, which fit 3 LEGO mini-dolls each, spin and wobble. Kids can then extend the play by pretending to serve at the cotton candy stall, imagining how fun it is to create the sticky pink treats. With a giant crab on top of the kiosk and turtle- and fish-shaped chairs, this LEGO amusement park ride is ocean-themed and looks pretty displayed in a bedroom. This fun playset includes 2 mini-dolls: LEGO Friends Mia and LEGO Friends Vicky.

  • Building kit includes 2 mini-doll figures: LEGO® Friends Mia and LEGO Friends Vicky.
  • Sea-themed toy features a rotating chair fairground ride, ticket kiosk and a cotton candy toy stall.
  • Accessory elements include a ticket, cash coin and bill, underwater elements, pearl element, trident, hair bow, sunglasses and cotton candy toy elements.
  • Combine with the LEGO® Friends 41373 Funny Octopus Ride and 41375 Heartlake City Amusement Pier LEGO rides to extend the action-packed fun.
  • This fun-packed sea creature toy ride makes an ideal Christmas gift or gift for the holiday season for creative kids.
  • This construction set is part of the LEGO® Friends world of everyday heroes and exciting real-world scenarios.
  • Amusement park toy measures over 6” (17cm) high, 4” (12cm) wide and 3” (9cm) deep.

Compare Similar Sets

The Underwater Loop offers a smaller and more accessible amusement park experience compared to larger sets like the Roller Coaster (41130-1). It's a good option for younger builders or those with limited space. While not as elaborate as some other Friends sets, it provides a fun and engaging play experience at a reasonable price point.

2 Minifigures Included

The set includes two minifigures: Mia and Vicky. Mia is a recurring character in the Friends theme, while Vicky features a unique yellow plaid shirt and glasses, adding a bit of exclusivity to the set.
