|Quest NPC?||Thok It To 'Em|
Thok refuses to go into the room with the ferret, due to him having furophobia, an irrational fear of ferrets. This makes the Ferret of Doom the only creature Thok could not beat. With a combat level of 9,001, 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, could have been highly exaggerated.
In Thok It To 'Em, Mini-marm, a pet crab found in the saga, may wander off at one point and return 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.
