It's going to be a cold Christmas as Santa struggles to find Frozen's top-selling doll
It's the Frozen toys that are sending parents in to meltdown.
Disney has a lot to answer for this year as children everywhere are going mad for merchandise of the hit movie Frozen and there is no sign of them "letting it go" anytime soon.
The magical film came out last Christmas and captured the imagination of young and old with its twist on the traditional Disney princess story.
But while Queen Elsa, Princess Anna, Olaf and Kristoff continue to warm the hearts of children, they are leaving parents cold as they struggle to find them.
And Santa's helpers have even been queueing overnight to get their hands on the most elusive gift of all - the singing, dancing and talking Snow Glow Elsa.
With a touch of her magical snowflake necklace, Elsa talks and her dress lights up. She also sings the hit theme song Let It Go.
Assistant store manager of Toys 'R' Us in Sprucefield said its last delivery of the dolls sold out in half an hour.
Richard Duncan said: "The main one is the Snow Glow Elsa doll.
"It is the main Frozen present everybody wants this Christmas.
"We got a delivery two days ago and got 24 of them and they were all gone within half an hour.
"I would say about 75% of our phone calls are customers asking for the Snow Glow Elsa doll - they are like gold dust."
Like many other stores they have plenty of other Frozen merchandise in stock but just not the coveted doll that has been carefully written on thousands of Christmas wish-lists.
Mr Duncan said: "I would like to think that this is the start of them coming in again but I would say it would only be in small amounts, not hundreds of them.
"It is always like this, this far from Christmas. There is that demand for them and then in the weeks closer to it we get the stock in and everybody usually seems satisfied.
"There are a few different things that are popular this year. The boy equivalent would either be the Transformers Stomp and Chomp Grimlock or the Dino Zoomer."
And it's not just Elsa dolls that are causing snowstorms.
Cool FM breakfast show presenter Pete Snodden was out on a desperate search for an Elsa Magiclip doll for his daughter Ivana.
He told the Belfast Telegraph: "Frozen is a massive hit in my house. My daughter Ivana has Elsa on the brain and even dressed up as her for Disney on Ice on Thursday.
"We have been trying for ages to track down an Elsa Magic clip which my sister-in-law found for us in a small shop in Ballynahinch. We had tried online and even had friends who were in the States and couldn't track one down in Disneyworld in Florida a month or so back.
"Anyhow now she has that it will no doubt be something else Frozen.
"I just hope Santa will be able to work his magic."
But not everyone has found themselves melting under the Frozen pressure as mother-of-three Abbie McKenna, from Newtownabbey, made sure she wasn't left outside in the cold.
The 37-year-old's daughter, Katie, is Frozen-obsessed, although the three-year-old is a bigger fan of the snowman character Olaf than Elsa. She said:"I start thinking about Christmas when the kids go back to school.
"So all the Frozen things were bought in the beginning of October.
"Katie loves Olaf, which is a little bit harder because a lot of the Olaf toys are geared towards boys. She likes him more than Elsa or Ana. He's her favourite in the film."
The little girl loves the film so much that they even have Frozen kitchen roll.
She added: "She's only three, so the little things are just as big for her."
