Ryan Tubridy believes it is "unrealistic" for tonight's 'Late Late Toy Show' to top last year's record ratings.
The 2013 show received average viewing figures of 1.4 million and Tubridy will be pleased if tonight's show comes close to that number.
"I have no expectation of exceeding that figure," Tubridy told the Irish Independent.
"I don't think we'll beat that record. If we can get close I'd be delighted."
The theme of this year's Toy Show is based on iconic 1968 musical 'Chitty Chitty Bang Bang'.
Tubridy will perform three separate music routines in the guise of lead character Caractacus Potts originally played by Dick Van Dyke.
"When I started doing the Toy Show I just had to jump out of a box and say, 'Hi' - then it became more," said Tubs.
"Singing and dancing was always a good idea, in earnest, in August - not so much in November though because singing is not easy and dancing is even harder. I've two left feet!"
Ryan will perform the opening number with 46 talented children.
"I will attempt to sing three songs in one, a medley feel to it - and, of course, the Chitty Chitty Bang Bang song," he revealed. "My head is melted from having it stuck in my head for the past six weeks."
RTE producers have decided not to include the character of the Child Catcher in tonight's show as they believed it could frighten younger viewers.
"They thought it was a bit dark to have a sinister creature offering lollipops to children," Tubridy explained.
This year, the toy count has reached an all time high - 200 toys are being tested out while a further 300 will decorate Darragh Treacy's colourful set.
Ryan will wear four different jumpers during the course of the programme - all of which have been hand knitted by members of the public.
"We asked the nation to submit jumpers and they responded with gusto," Tubridy said.
"Some of the knits were truly breath-taking. They were things of great wonder."
Some 269 performers and toy testers will take part in the broadcast, with 46 children taking part in the opening routine. All the toys on the show - which kicks off at 9.30pm on RTE One tonight - are donated to good causes afterwards. The show will also be available on the RTE Player for three weeks after the show.
"Being on the Toy Show is magical," Eva Campbell (12) from Skerries said. "I have watched it since I was little so I can't wait."
So, did you manage to get your hands on a Frozen "Elsa" Glow Doll yet? If not, do you know anyone who was lucky enough to do so? (You may be able to negotiate your yearly salary in exchange for it). Does Santa have any left? More importantly, has Ryan Tubridy and the Toy Show team been able to put their hands on one for tonight's Christmas show (see below left)? And the question on everybody's lips today - will there be one for everybody in the audience?
