Begin by greasing a large plate to prevent sticking. In a medium saucepan over medium heat, combine the sweetened condensed milk and cocoa powder. Stir continuously as you add in the salted butter for about 7-8 minutes until the mixture thickens.

Carefully transfer the fudge mixture to the greased plate and spread it out evenly. Allow it to cool at room temperature, then chill in the refrigerator for about 30 minutes.

Wash and dry the strawberries thoroughly. Once the fudge has cooled, wet your hands with a bit of water, scoop a portion of fudge, and mold it around each strawberry.

Roll the fudge-coated strawberries in grated chocolate or sprinkles. To create tails, shape a small piece of fudge and attach it to the back of each covered strawberry. Use roasted peanuts for ears.

Chill the decorated fudge mice in the refrigerator for at least 15-20 minutes to help everything set firmly.
