Overview[1][2]
Leedsichthys is a Legendary catch in Fisch, found around Ancient Isle — sells for about 2 C$ per kg. In-game bestiary: “Leedsichthys is a colossal, plankton-feeding fish from the Jurassic period, approximately 165-150 million years ago. It is one of the largest fish ever to exist, showcasing the diversity of prehistoric marine life.”
The Leedsichthys is a Legendary fish that can be caught at the top of the waterfall on the main island of Ancient Isles. Due to its rarity, it moves erratically across the fishing bar, making it a challenging catch. When catching, a -25% progress speed decrease is inflicted on the player. When hooked, an exclamation icon will pop above the player's head, and a bell sound is played - as with all Legendary fish.
