Radioactive Blue
An accidental by-product of an experimental drug, this cheese was created during a chemical spill of a volatile potion. Native to the Laboratory, the experimental mice have found this new type of cheese extremely appealing. Eating it may or may not give you super powers. Use at your own risk.
Overview
Radioactive Blue Cheese is a special cheese used for attracting a number of Shadow mice, and also has the ability to attract a few other mice such as the Monster.
Our standard price for Radioactive Blue Cheese is 500 gold per piece.

| Location | Attraction | Cost Effectiveness |
| Catacombs | Good | ![]() |
| Laboratory | Near Perfect | Not yet done |
| Mousoleum | Very Good | ![]() |
Please note:
Attraction is based on the Base Attraction for the cheese – please remember this can be improved by using a trap with an Attraction Bonus.
Cost Effectiveness is based on the standard price for the cheese: At least one star is good, a red cross indicates a potential loss.
Special Properties
Radioactive Blue Cheese is the only known cheese to reliably attract the following mice:
![]() Monster |

Why is it that Cost effectiveness is only 3 stars for Mousoleum? The total profit and points is almost the same than at Catacombs.
It has more to do with the fact that not enough reports have been sent in to analyse I suppose?
Same with the laboratory. I find that I’ve hunted with radioactive blue there so often (in order to attract monster mice for those greater potions) that it comes to slightly above even. Yet here it says not enough data.
Legendary rank can brew 42 cheeses from the Greater Blue Potions.
Thanks, are you able to tell me how much with SB+?
