Rodent's Revenge is a Windows puzzle game written by Christopher Lee Fraley and published by Microsoft in 1991 in the Microsoft Entertainment Pack. You play a mouse who pushes blocks around a grid to box in the cats chasing you — trap them all and they turn into cheese, and the next level begins.
This hat
The squeak shall rise. The cheese shall flow. This corduroy hat is a symbol of the coming revolution. Wear it as a warning to the feline oppressors, a beacon of hope for the cheese-loving resistance, and a reminder that sometimes the smallest creatures hold the biggest grudges.
