Frogfly guide
Frogfly is a Mythic, yet at $1.25M/s only one of the 23 Mythic pets in the game, Citadel Snail #007, earns more. It's the starting point of the Unstable Egg, the pool behind the Unstable DNA banner in Dr. Scramble's Laboratory.
The banner that reaches into Angels & Demons
Update 6 replaced the Rift Trade-In Machine with the Laboratory and added three rotating banners. Unstable DNA is the one that draws from the most advanced eggs: Cosmic, Cherry Blossom, Titan Temple and Angels & Demons. From that last biome it accepts Light Dove and Flame Sprite (Legendary), Winged Lamb and Toro (Mythic), four Cosmic pets, and the Secrets Gargoyle and Pure Jellyfish. Since Update 6 you can trade in eggs directly, and hitting pity guarantees the banner's top reward.
A detail worth noticing: Toro and Winged Lamb, which this banner accepts, earn exactly the same $1.25M/s as Frogfly. If you're short on other requested pets, trading one of them away costs you nothing in income compared with what Frogfly gives back.
