Ferrety and Ferrlicity are helping out the Spook Squad with their mission. Ferrety, on the left, will take care of the shop, offering our heroes new dice and modules. As long as you have enough Ghost Jars that is.
Ferrlicity, on the right, mans the blacksmiths. This is the place to go if you already have a great set of dice and want to make them even more powerful. She'll take your Ghost Jars and boost the values on a dice much higher than the dice you could find in the current level. Maybe even as high as dice on the next level.
The Ferret Sisters are pretty renowned throughout the Fuzz Force, everyone knows about their handiwork. It's pretty lucky they have a strong interest in the paranormal.
