There are 2 tameable creatures with this look.
|60||Catalyst Gardens, Zereth Mortis|
|The red and bronze variants of this annelid seem to be far rarer than the other two colours (perhaps only a tenth of the frequency).|
|Untamed Verdure, Zereth Mortis|
|Retains its original name after taming.|
The Unbroken spawns as a trio of worms, each with a different NPC ID, but only the one with this ID is tameable. They can appear in two colours, and if you're unlucky you may have to kill all of them and wait for respawns until your desired colour appears. Their respawn time is only a few minutes.
