Remove cookies from the package and put them in a chopper or food processor.
Place the cookie crumbs in a large bowl.
Remove room-temperature cream cheese from the foil and microwave for 20 seconds to make it extra creamy and easier to work with.
Combine the cream cheese with the cookie crumbs and stir till well combined. Cover the bowl with plastic wrap and place in the fridge for 30 minutes.
Remove the bowl from the fridge and cover a cookie sheet with wax paper. Form the mixture into small balls (a little smaller than a gum ball) and place on the wax paper.
Fill the cookie sheet with the balls and place in the freezer for 10 minutes to become firm.
For the Bats
Draw out a few small wing shapes onto a piece of paper. Lay some wax paper over the top and tape it to the table top.
Melt a small amount of chocolate according to the package and transfer to a Ziploc bag. Snip a small corner off of the bag and pipe the chocolate following the stencil. Allow to set for a few minutes, or speed up the process by tossing them into the fridge.
Melt a larger portion of chocolate. Dip each of your prepared truffles (one at a time) into this and quickly apply the wings, eyes, and mini chocolate chips for the ears. Let them set up before handling too much.
