The sink-crab was a crustacean native to Bestine IV. It used bladders that filled with air to propel itself. Jek Tono Porkins once hunted these creatures in his T-16 skyhopper.
Behind the scenesEdit
In the first edition of Galaxy Guide 1: A New Hope, they were referred to as "flink-crabs" in Porkins' biography. It was changed to "sink-crabs" for the second edition.
