Gorillastein guide
Gorillastein earns $3.5B/s, making it the 4th-best of the 36 Eternals, more than double the Eternal median of $1.5B/s. It shares the figure with Pumpkin Brute and, interestingly, with a Divine, Shattered Colossus. In the Halloween Dimension it ranks 3rd of 29. Engine Snail at $3B/s sits just below it.
This is one of the thinner records in the batch. The wiki gives the Gorillastein Egg but no hatch reward, no grow time and no weight, so there is nothing to say about how the egg behaves. What the data does support is the income comparison and the mutation ceiling.
Silver would reach about $4.2B/s, Golden $8.75B/s and Rainbow $12.25B/s. A Golden Gorillastein would pass the unmutated Bone Emperor ($7.5B/s), a Divine pet from the same dimension, and Rainbow would sit just under Voidseer Pumpkin's $14B/s. That makes it a strong mutation candidate, if you can find the egg. Within the dimension, only Bone Emperor and Voidseer Pumpkin earn more than the plain version.
