Meet Mel, Darryl and Roy, the best kept secret in the North Pole! At just 150 years old (in Santa years), Mel, Darryl and Roy have a lot of growing up to do - both in maturity and around their waste lines! The time has come for Santa to decide who is going to take over the reins of the big sleigh, but is becoming clear to him as the icicles that hang from his workshop windows that the triplets are more likely to enjoy monkey business than the family business! So to prepare them for the job Santa and Mrs Claus decide to teach their triplets the true meaning of Christmas and enlist Santa's right-hand elf, Snorkel, to show them the ropes. But what Saint Nick doesn't know is that Snorkel has greater plans and hopes to over-throw the whole family and gain Santa status for himself!
