Overview[1]

Colossal Blue Dragon is an Exotic fish found in the Luminescent Cavern.

The Colossal Blue Dragon is a Exotic fish obtainable in a abundance located to the left of the Luminescent Cavern during a Colossal Blue Dragon hunt. Due to its high rarity, it makes for a challenging catch, moving erratically across the fishing bar. When reeling it in, a -90% Progress Speed is applied. When hooked, a will pop above the player's head, and a shimmering sound is played - as with all Exotic fish.

What does this mean?

Fisch's in-game currency. A fish's value is its documented average sell price in C$ — what it sells for at its average weight. A rod's value is its documented shop cost. Both are in-game facts from the community wiki, not a trading consensus. Values are not comparable across games.

Trivia

The Colossal Blue Dragon is based on the real world species called Glaucus atlanticus, or the Blue Glaucus. It is a species of small sea slugs that float upside-down near the ocean's surface, with a gas bubble located in it's stomach allowing for it to have buoyancy. This is mentioned in the description of the fish, where it is seen by sailors through its brilliant blue shine reflected off from the sun. The average KG listed in-game is heavily inaccurate to the real Blue Glaucus species, as they can't even exceed 100 grams (0.1KG) in weight. The Blue Glaucus species is also armed with toxic stinging cells, which are its main defense system. You will need a Crimson Colossal Blue Dragon to enter the Crimson Cavern. One way to get this easily is to appraise the Colossal Blue Dragon during a Mutation surge for a 0.26% chance to obtain the Crimson mutation.
