LEGO City 3178, Seaplane, depicts a small floatplane connected with the City harbor setting.

Set 3178, Seaplane, belongs to the Harbor branch of LEGO City. Its subject is a light aircraft for water based scenes, fitting naturally beside docks, coastal routes and civilian transport stories within a broader City layout.

The build focuses on a compact seaplane made from 102 pieces. That description identifies a dark blue plaid shirt, dark blue legs, a red cap and silver sunglasses.

The set suits play, a small display or a collection of civilian City vehicles. Within the Harbor setting it adds an aviation element to an environment otherwise associated with water, quays and boats. It can be placed as a connector between harbor scenes and wider urban layouts rather than as a stand alone licensed subject.
