After School Hub is building up to a very special guest on Friday, 18 December. To give you a hint he has a beard and wears a red suit...

But, before the big man is coming to the show he has sent two of his special agent elves Holly and Jolly to keep an eye on things.

They can zap in and out of the Hub and even make themselves so small no-one even notices them. Tune in all week to see what kind of fun and messing they get up to, they even secretly join Muinteoir Emer in her Zumba class today!

Tune in to After School Hub all week from 3.20pm on RTÉ2!
