Mousoleum
"The scientists of the nearby Laboratory would often come to the Mousoleum to harvest 'spare parts' for their various creations. This grim hunting location is now haunted by spirits of slain mice. The mice of this location seem almost unable to resist radioactive cheese."
For a hunter to access the Mousoleum, he/she must obtain an Ancient Tattered Cloth from a Zombie Mouse in the Laboratory.
The Mousoleum contains much stronger mice than previous areas. This means there is more risk, but also more rewards. There are ghost mice in the mousoleum, as well as some strong physical mice. Here's a list of the mice: Mutated White, Mutated Grey, Zombie, Bat, Vampire, Ghost, Mummy, Ravenouse Zombie, Monster, Lycan, Black Widow.
There are specific traps designed for use in the Mousoleum, these are the Sinister Portal, and Ambrosial Portal. These can be bought from the Town of Digby. The portal traps are weaker than the Swiss Army Trap, but they have a strong multiplyer for the ghost type mice. Most people agree that this is the best trap for the Mousoleum.
Radioactive Blue cheese is commonly agreed as the best cheese to use in the Mousoleum. It has a much better attraction rate for the ghost mice.
