Twenty-first narwhal

#21: Lamppost. Helpful as ever, the narwhal has now taken to lighting people's way home. He has decided to impersonate a lamppost! Unfortunately, in the process of gaining this disguise, a real lamppost was uprooted and decapitated. Then how, you ask, is the lamp glowing when it has been so rudely disconnected from its wires? Well, it's simple- it runs from the narwhal's joy.
