Pet income multiplier curve
Common pets earn 1x base income. Uncommon earn 2x. Rare earn 4x. Epic earn 8x. Legendary earn 16x. Stack these with treadmill boost and you can reach ~$77,000/s with a Legendary Lava pet (verified quote from Andy Plays). Mythic bases reach ~$500,000/s (verified Desert-zone Mythic observation).
Hatch time per egg tier
Common eggs hatch in ~30 seconds. Rare eggs hatch in ~2 minutes. Epic eggs hatch in ~8 minutes. Legendary eggs hatch in ~25 minutes. Mythic eggs (Cosmic, Lava variant) hatch in ~5 hours. Plan your inventory around these timers.
Rare-egg race cadence
Every ~5 minutes, a server-wide rare egg spawns at one of 5 fixed spawn points. First to grab wins. Pre-position for the rotation. The cadence is consistent across both the beginner and noob-to-pro guides.
Variant ladder
Eggs roll variants: Normal / Gold / Rainbow / Shiny bands. The variant ladder above is Divine / Eternal / Secret / Mutated / Huge / Standard. Divine is the endgame cap; no individual IDs are publicly named.
