Olive flounder

The olive flounder is a fish you catch in the sea. Look for a very large shadow. In the northern hemisphere it is around all year, at any time of day. Nook's Cranny pays 800 Bells, C.J. pays 1,200 Bells.

An X-Large sea shadow around at all hours, all year. It often raises false hopes when you are chasing rarer giants, but still sells for 800 Bells.
