This is a myth. it seems to be part of the Santa Mythus that the Reindeer and the jolly old elf have an added superpower of altering their size and shape so they can get down chimneys- the poem alludes to this- eight Tiny Reindeer. Rudolf is NOT mentioned in the original poem- by Clement Moore. The shape shifting bit is also a sort of camouflage device- but Mr. Moore could not have anticipated Radar. ( he was writing in the nineteenth century).
