Engine Snail guide
Engine Snail earns $3B/s, 6th of 36 Eternals and exactly double the $1.5B/s median. Two Divines, Nightflame and Cthulhu, earn the same figure, so this Eternal matches pets a rarity above. Pink Dragon Experiment #010 ($2.5B/s, Event) is just below, and Gorillastein ($3.5B/s) from the Halloween Dimension just above.
The wiki lists an Engine Snail Egg, but not a source, a hatch reward, a grow time or a weight. A racing or mechanical theme is easy to imagine from the name, yet nothing in the data supports one.
Mutation arithmetic is the substance here. Silver reaches about $3.6B/s, Golden $7.5B/s and Rainbow $10.5B/s. The Golden value equals Bone Emperor's plain $7.5B/s, a Divine, and the Rainbow value is above every plain Divine except four: Cursed Monarch, Voidseer Pumpkin, Zombified Bone Emperor and Spirit World Guardian. For an Eternal with an unknown origin, that makes it a pet worth keeping if it falls into your hands.
