Deep Mouse

Hunt in this location: Iceberg > Deep Lair
Base: Deep Freeze Base
Bait: SUPER|brie+, Gouda Cheese
Note: Hunters must arm the Deep Freeze Base to catch Icewing Mouse and then complete the Hidden Depths in fewer that 250 hunts to enter The Deep Lair and encounter this mouse. The Deep Freeze Base is not necessary after having caught Icewing Mouse, so a more powerful base can be armed as Hunters target this mouse. This mouse is a guaranteed catch on hunt 250, but only if attracted to the Hunter's trap. Therefore, it is recommended that Hunters arm SUPER|brie+ for that final hunt.

Finally solving the question as to how the Iceberg is propelled, the Deep Mouse lives well below the Iceberg, dragging it relentlessly towards the shores of Gnawnia.

Only the most dedicated hunters will ever be able to encounter this monster, let alone defeat it!
