What are the mice?

For a while, we have all been wondering, What ARE the mice? Well, we have recently found out. The white mice (excluding M.O.M., more on that soon) are all Folkmanis Three White Mice in Red Box, which checks out with the red box we found Trey, Curly, and Rosy in. The original brown mouse is a Ourpets Mousehunter Play-N-Squeak Realmouse, and the more recent brown mice are Folkmanis Three Brown Mice in Green Box. But then, what is M.O.M.? We have a few theories. 

• She was part of a vintage three white mice in a red box, and we are still to find the other two

• She was sold individually or is a old prototype

• She was either of the above and came as a small extra with a box of patterns.

We hope to soon find the answer to this mystery!
