Explorer Submarine (Qiji 2414)

About this set

This KEEPPLEY 2414 Explorer Submarine sits in the Crystal series' deep-sea mission line, and the box lists 401 pieces with a 6+ age mark and a 2/5 difficulty rating, so it is a light build rather than a long project. The finished sub is mostly yellow with black and red accents, a transparent spherical cockpit up front, twin propellers at the tail, and a mechanical arm mounted on the hull; the scene adds a minifigure, a shark, seabed rock and coral, and seaweed, with blue and transparent parts carrying most of the underwater mood. Build the hull in sections first, then seat the transparent cockpit dome, and attach the propellers and arm last so you do not crush interior parts while closing the shell. Save the rock, coral and seaweed for after the sub is done, which makes it easier to place the shark and adjust the layout. At 2/5 the clutch is forgiving for younger builders, though the dome and arm joints are the spots that need a second look. With 401 pieces it works as a compact display set for anyone who wants a small deep-sea scene without a big part count.
