Streeler

The Streeler is a giant snail native to Africa, but has been successfully bred by wizards in Europe, Asia and North America.

Behaviour
The Streeler changes colour hourly, 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.

History
The "poisonous orange snails" seen in the Magical Menagerie in 1993 may have been Streelers.

Protection from Streelers
Wearing thick protective gloves is a way to avoid getting stung by a streeler's extremely toxic shell.
