LEGO® Hydronauts Sets

How to read this plate

1. Each island is an era of the theme, larger for more sets.
2. Each dot on an island is one of its sets; larger dots have more pieces.
3. The dotted route joins the eras in the order they came, and the years beside it are the years it sails through.

Painted in Hydronauts's own bricks: the colours its parts use far more often than the rest of the catalog does, on Light Gray.
