|Quest NPC?||Thok It To 'Em|
Thok refused to go into the room with the ferret, due to him having furophobia (an irrational fear of ferrets), making the Ferret of Doom the only creature Thok could not best. With a combat level of 9001, the Ferret of Doom holds the record for the highest combat level of any monster in RuneScape, however, it is not attackable, and as with most other events in Thok's story, it could be highly exaggerated.
Thok cannot kill it, but Mini-marm wanders off at one point and returns with his claws dripping blood and the Ferret of Doom's head as a trophy.
In Thok Your Block Off, the Ferret of Doom makes a reappearance, but this time appears with several friends, scaring Thok off once again.
