Rolly is one of the fifteen biological puppies of Pongo and Perdita in the 101 Dalmatians franchise. He is always hungry, which sometimes gets him in big trouble. In the first film, Rolly and his 14 siblings live in London with their parents and owners Roger and Anita. Rolly, his siblings and 84 other Dalmatian puppies, are kidnapped by Jasper and Horace on the orders of Cruella De Vil who wishes to use their skins to make a coat.
Fortunately, Pongo and Perdita are able to find them and bring them back home where Roger and Anita decide to adopt the 84 other puppies. Rolly, along with Lucky, Cadpig, and Spot, is one of the four main characters in the 1997-1998 TV series, in which he is voiced by Kath Soucie. In the original film, he had been voiced by Barbara Baird.
