Barney the giant purple dinosaur, which delighted children in live shows over Christmas, will be at the Go outlet in South Street, Valletta, on Tuesday between 12.30 and 1.10 p.m.
Children can take a photo with Barney while parents can avail themselves of some offers from the telecoms company.
Visitors will be able to take part in a competition that could win them four tickets to the Barney show, a Barney soft toy, a Barney figolla and a choice of Barney books, or collectibles, among other gifts.
