Empath: The Luckiest Smurf stories
Empath and the Smurflings come across a lone reindeer in the Smurf Forest with a red nose that has the power of illumination, which they give to Mr. Nicholas on a foggy Christmas Eve to guide his sleigh safely through the dense fog created by Chlorhydris the witch in the EMPATH: The Luckiest Smurf story series. The reindeer was given the name of Rudolph by Nicholas himself.
