Fox has unveiled the couch gag from this year's Simpsons Christmas special.

The animation's intro is full of Christmas cheer and festive fun as Springfield is transformed into a winter wonderland.

There is even an 'obligatory Frozen reference' as Lisa creates an ice tower and Homer is turned into Olaf the snowman.

The couch gag is quite similar to last year's intro, with a few added differences, including Maggie sharing a rare moment of warmth towards Gerald, the unibrowed baby.

The clip will feature in this year's festive special 'I Won't Be Home for Christmas', to be broadcast on Sunday (December 7) at 8pm in the US.

It will air on Christmas Eve at 8.30pm on Sky1 in the UK.
