Download the zombie template, print, and cut out the pieces you need.
Begin by gluing the eyes just above the undereye wrinkles.
Next, take the shirt and glue it to the bottom of the zombie body, so it lines up with it.
Place the brain near the top of the zombie's head and glue it in place.
Take a piece of tape and place it on the end of the zombie. Secure this end to the toilet paper roll. Take another piece of tape and place it on the other end of the zombie. Wrap it around the cardboard tube and tape it in place.
