Cut the cheese logs into pieces for the head, body, two arms and two legs. Arrange them on a serving platter so the pieces touch.
Beat the softened cream cheese and milk until smooth. Spoon it into a piping bag fitted with a #47 basket weave tip, or into a zip-top bag with a small corner snipped off.
Pipe crisscrossing rows of bandages over the mummy, leaving small gaps so the cheese shows through.
Press in the peppercorns for eyes and add the pimiento strip for a mouth. Chill until ready to serve.
Notes
Make ahead: Assemble up to 1 day ahead, cover loosely and refrigerate. Let it stand 15 to 20 minutes before serving.No #47 tip? A zip-top bag with a small corner snipped off works fine.
