SAMMIE the dog is showing Swadlincote sleepwalkers the way ahead of a trek around the town which takes place tonight.
The onesie-wearing walkers will set off from Sainsbury's, in Civic Way, at 8pm, and are expected to finish two hours later.
The walk has been organised by Burton YMCA, with the event having raised thousands of pounds for the charity in recent years.
Sammie belongs to YMCA chief executive Paul Laffey and was photographed in sleepwalk attire ahead of the big night.
People can register on the night at Sainsbury's from 7pm.
