Cut carrots into rounds at the thickest end so that you have 5 thick rounds. Cut top hat shapes out of the rounds with a small paring knife.
Now cut remaining carrots into rounds at the thinner end so that you have 2 thin rounds. Trim those so that you have 5 small triangle noses.
Add 3 bagel bombs to each skewer, making sure the ball with the peppercorns is at the top. You should have 5 snowmen skewers.
Carefully stick on the carrot hat into the skewer point so that it’s secure. Wrap around a scallion scarf. Use the reserved cream cheese to attach the carrot noses to the faces.
