- Base weight: 1,000 kg
A Legendary that earns like a Mythic
Crustacia's income is higher than several Mythic pets from earlier zones. The Ankylosaurus from Prehistoric makes $120K/s, slightly less than this Legendary. Within Titan Temple, though, the gap to the zone's Mythic, the Bladehide ($750K/s), is still large.
Compared with the Spideron, the trade is clear: both pay +2.7m Speed and $13m on hatch, but Crustacia earns about 37% more per second and takes two minutes longer to grow. If the pet will stay in your pen earning, Crustacia is the stronger keep; if you are cycling eggs for rewards, the Spideron finishes sooner.
Rankings
- 7th of 8 in Titan Temple

What mutations and weight could add
Following the wiki's documented formula (its calculator is marked beta), these are the estimates:
- Golden: about $325K/s
- Rainbow: about $455K/s
- 10× base weight: about $538K/s
- 100× base weight: about $2.22M/s
- 200× base weight: about $3.08M/s
- Rainbow with 100× weight: about $7.79M/s
A 100× Crustacia would outearn an unmutated Bladehide almost three times over.
