A moonwalking Shetland pony that shot to fame in an advert seen by millions is set to return to screens.

A video of Socks strutting his stuff to the tune of Fleetwood Mac's Everywhere went viral earlier this year, notching up more than seven million hits on YouTube.

The dancing pony will star in a second commercial for mobile phone network Three, set on the beaches of Shetland.

The company has teamed up with VisitScotland and Promote Shetland for The Knitwear Before Christmas campaign.

Socks will be kitted out in a Fair Isle Christmas sweater created by Shetland designer Doreen Brown in accompanying print adverts.
