Coraswan

A "Coraswan" is both the name of an invention of a peddling boat shaped like a swan by Corazón, and the nickname Merilwen gives him after this invention was created.

The first two boats made had distinct faces on them, one of which is a near-perfect replica of Corazón's face on a swan's neck. The other figurehead was a fist clutching an unconcious squirrel. It is unknown how Corazón was able to create these, nor how long it took, or where he acquired the materials.
