Blastcrab

Blastcrabs are round creatures native to The Tundra, usually found in the dark gray areas.

During the day, Blastcrabs can be seen sleeping. They cannot be harmed when sleeping.

They wake up at night, from about 09:30 P.M. until 07:00 A.M.

Taming
Once you find a Blastcrab Egg, you can hatch it with a Blastcrab Incubator.

To embiggen your Blastcrab to Powerful level, you need a Blastcrab Firebarrel.

To embiggen your Blastcrab to Epic level, you need a Cooler.

Tame Blastcrabs produce Blastcrab Hydrocarbon.

Attack Pattern
Blastcrabs only become active and start attacking at night. Once they have begun to attack however, they will continue to attack as long as you are in range, even if the sun has risen.

They have two similar attacks, both of which involve launching themselves explosively into the air.

In one attack, they land back on the spot they launched from with another blast.

In the other attack, they land further from the launch site but with a smaller area of damage.

They do damage when they launch and when they land.

Fighting tips: Blastcrabs are immune to fire damage but have low resistance against other attacks. Escaping from their attack site can be difficult (especially if you are not good at controlling flux, have low move speed, or move too late.) Best items for this creature are Nematoblaster and Slowball Machine which deal ice damage, make them move slower and take 25% more physical damage. If you are good at running and escaping, the Space Wrench and Stunning Mirror can also help. Electric devices are recommended to do some good damage.

Trivia

 * Blastcrabs actually have faces, and limbs.
 * When enbiggening a Blastcrab to Epic, the face and arms/legs are visable.
