Ferret (Dungeoneering)

Ferrets underneath Daemonheim play a key role (literally) in certain Dungeoneering puzzles. In all the puzzles the ferrets must be either captured, or enticed to move onto pressure plates to unlock the doors out of the room. The ferret-related puzzles are Fishing Ferret, Hunter Ferret, and Coloured Ferrets.

Ferret of Doom
In the Thok It To 'Em saga, players, as Thok, can encounter the Ferret of Doom, an immensely powerful ferret with a combat level of 9001.
