Mecha Crawler hatches from the Mecha Egg, part of the Mecha Egg group. According to the wiki, limited eggs like this do not spawn in the regular biome nests: they come from the Store or from special events such as Admin Abuse.

Mecha Crawler guide
Mecha Crawler sits in the middle of the Mecha line at $320M/s, almost exactly double Mecha Froggo below it and about half of Mecha Crocodon above it. Against its own plain form, Crawler at $1.5M/s, it's roughly 213 times better.
Origin of the Mecha variants
In Update 2 the Monster Egg went on sale in the Robux Store with six monsters, and every monster was given a rare Mecha variant. The wiki groups the six variants under a Mecha Egg. It also describes the Monster Egg as limited, and Update 4 replaced it with the Luminous Egg. The odds of a Mecha roll aren't published, and neither are a grow time or a hatch reward for Mecha Crawler.
Mecha Crawler among peers
- 4th of 6 Mecha pets; 6th of 12 Monster-rarity pets.
- Slightly above Dunkleosteus ($300M/s), the plain Secret from the extinct line.
- Below the plain Krakenoid ($500M/s), so a Mecha roll on Crawler still doesn't catch the monster two steps up.
- 52 of 198 pets in the game earn more.
Weight and mutation estimates
Every Monster-line pet shares a 35 kg base weight, so a 100x Mecha Crawler shows about 3,500 kg on its card. With the formula the wiki documents:
- Golden: about $800M/s
- Rainbow: about $1.12B/s
- 10x base weight: about $1.32B/s
- 100x base weight: about $5.48B/s
- 200x base weight: about $7.58B/s
- Rainbow at 100x weight: about $19.2B/s
A Golden Mecha Crawler would beat a plain Mecha Crocodon, and a 100x one would pass a plain Mecha Dreadscale ($4B/s), the top of the line. If you're comparing copies, weight is the bigger lever: a 10x roll is worth more than a Rainbow one.
