Lego fanatic Finn Ryan from Ferrybank was a huge hit on tonight's Late Late Toy Show.
The eight year old told Ryan Tubridy that he beat cancer earlier this year, and rang a bell on the hospital ward to herald the end of treatment.
After Finn talked us through his lego display, he was brought over to ring a bell on set, this time in front of a global audience of millions!
The icing on the cake came when Ryan Tubridy told him he and his family were going to Legoland.
