Rescue Vessel Set (Qiji 3712)

About this set

This is the KEEPPLEY Rescue Vessel Set (3712) from the Octonauts series, with 429 pieces on the box and a 3+ age mark. The finished model is a submarine with a transparent canopy, a mechanical arm and propellers, plus two minifigs, and it pairs with an underwater scene to stage the explore-rescue-protect theme. The color scheme leans on yellow, green, blue, orange and white for a bright look. At a 2/5 difficulty, build the hull and propellers first, then attach the canopy and arm, and place the minifigs last. The transparent parts and arm joints are the main tricky spots, so line up the clutch carefully. It suits Octonauts fans and young parent-child builds, and the official license helps the characters read correctly.
