He is covered in snow so you blow him with the leaf blower that can be found in Greg's garage. You will get access to the garage once you turn off the music in Rodrick's room and Rodrick leaves, which moves his car out of the driveway.
Also, you turn off the music by getting into Greg's laundry room. You will eventually be able to open the door. Rowley will give you the membership card/key.
