Ernie Clicker is one of Santa's elves from Arthur Christmas.
He served as Head of Polar Communications during Grandsanta's time as Santa.
In the present day, Ernie is brought out of retirement by Grandsanta's grandson Steve and his elf assistant Peter to his communication device to contact Grandsanta, who along with his other grandson Arthur and an elf named Bryony Shelfley, left The North Pole in his old sleigh Evie to deliver a bike that had not been to delivered to a girl named Gwen in Cornwall. Ernie receives a message from Evie that sounds like gibberish. Unbeknownst to Ernie, Steve and Peter, it was because Grandsanta, Arthur and Bryony were being attacked by lions after they mistakenly landed in Africa. Afterwards, Ernie's device malfunctions and causes a power cut in Mission Control.
After, the elves proceed to activate a shutdown of Christmas, out of belief that the Claus family have abandoned The North Pole, Ernie narrowly misses getting crushed by a Santa ice sculpture. He then notices on a screen in Mission Control that Arthur has arrived in Cornwall and is delivering the bike to Gwen. He alerts the other elves to this, which makes them stop the Christmas shutdown.
