Where to get Crawler
Crawler hatches from the Monster Egg, part of the Monster 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.

Crawler guide
Crawler is the middle child of the Monster Egg: fourth of six monsters at $1.5M/s, a big step up from Froggo ($50K/s) and well short of Crocodon ($30M/s).
How much the Mecha roll is worth here
Update 2 introduced the Monster Egg in the Robux Store and noted that every monster has a rare Mecha variant. Crawler's is Mecha Crawler at $320M/s, about 213 times the plain income. What's interesting is how that multiplier changes along the egg:
- Scorpio to Mecha Scorpio: about 4,500x
- Froggo to Mecha Froggo: about 3,100x
- Crawler to Mecha Crawler: about 213x
- Crocodon to Mecha Crocodon: about 23x
- Krakenoid and Dreadscale to their Mecha forms: 2x
So the Mecha bonus matters most at the bottom of the egg and shrinks as you go up. Crawler sits right at the point where the jump is still huge. The wiki doesn't publish the Mecha odds.
Availability
The wiki's Monster Egg page calls it limited and sold for Robux, and Update 4 replaced it with the Luminous Egg. There's no biome nest to steal it from, and the wiki lists no grow time or hatch reward for Crawler.
Plain Crawler estimates
Crawler ranks 10th of 12 Monster-rarity pets, and 108 of 198 pets in the game earn more. Base weight is 35 kg, shared by all six Monster Egg pets. Using the formula the wiki documents:
- Golden: about $3.75M/s
- Rainbow: about $5.25M/s
- 10x base weight: about $6.21M/s
- 100x base weight: about $25.7M/s
- Rainbow at 100x weight: about $89.8M/s
A heavy Rainbow Crawler would outpace a plain Crocodon three times over, but still sits far below its own Mecha form.
