The poison crawler is hostile mob found in the Deep Woods. The poison crawler is an orange caterpillar-like creature with two large mandibles. The poison crawler does not burn in the daylight, making it a danger to the player even during daytime hours.
The Poison crawler has 16 health (8 hearts) and does 5 damage (2 and 1/2 hearts). As the name suggests, it can sometimes poison the player for four seconds. The poison crawler is an arthropod, and is thus vulnerable to the Bane of Arthropods enchantment.
Poison crawlers can also be found in the poison forest biome, but their spawning there is dependent on thorn wood.
Poison crawlers will join in mob sieges against the player's home in the deep woods biome.
