Aquatic : Flame

The jump from Aquatic to Aquatic : Flame is a clean example of how mutations scale. The Sol's RNG Wiki lists Flame as a Mythic mutation of Aquatic added in Era 2 and found by clicking on Aquatic in the collection, rolled at 1 in 4,000,000. The parent is 1 in 40,000, so this version is exactly one hundred times rarer. At luck 1x you would expect about 4 million rolls, and about 400,000 with 10x luck. It is credited to idkaple.

Where Aquatic is blue and calm, this one burns. The two rotating whirlpools are much larger and a bright fiery orange, with faint orange electricity under them. The player gets flames on the arms, a halo that leans slightly backward, a blazing star in the chest and three flaming stars that revolve very slowly alongside the whirlpools. The wiki lists several earlier cutscenes, including Era 6 and older ones.

Trivia says the colon in the name is drawn as a bullet by its font, Sarpanch, and that the first player to obtain it was rokiesss.
