Other Eternal pets
Skeletal Gigantus guide
Of the 24 Eternal pets the wiki lists, Skeletal Gigantus earns the most: $4B/s. Every pet above it in the game's income table is a Divine.
From Gigantus to bones
The base Gigantus is already an Eternal worth $1B/s. Its skeletal form quadruples that and keeps the same rarity, unlike Skeletal Dunkleosteus, which jumps from Secret to Eternal.
The route comes from Update 6. The new paid Extinction Egg holds six extinct animals, and the patch notes say each hatch has a small chance to reroll into a rare skeletal version of the animal. The wiki does not give that chance, and it groups the skeletal results with some of the base animals under a Skeletal Egg. To end up with Skeletal Gigantus, a hatch has to give Gigantus and then trigger the reroll.
Where it lands
- 2nd of ten pets in the Skeletal Egg group, behind only Skeletal Sabertooth at $9B/s.
- 8th of 198 overall.
- Tied on base income with Octophant and Mecha Dreadscale, both from limited or Laboratory sources.
Estimated income with size and mutation
The wiki lists a base weight of 35,000 kg. Using its documented formula:
- Golden: about $10B/s
- Rainbow: about $14B/s
- 10× weight: about $16.5B/s
- 100× weight: about $68.5B/s
- 200× weight: about $94.8B/s (diminishing returns apply past 125×)
- Rainbow at 100× weight: about $240B/s
A Golden copy alone would out-earn a base Skeletal Sabertooth, the top pet in the game, which shows how much the mutation roll matters at this level.
