The Streeler changes colour on an hourly basis, and leaves behind a trail of venom so toxic that it burns all vegetation that it touches.
Kept as pets
It is kept as a pet by those who enjoy its Kaleidoscopic colour changes. Streeler venom is one of the few known substances that can kill Horklumps.
Protection from Streelers
Wearing thick protective gloves is a way to help from getting stung by a streeler's extremely toxic shell.
