Rolly is known for his excessively large appetite. He can be gentle and care-free at times but after his family, food may be his true love. Even after just eating, Rolly can be seen asking for food and the only one of the puppies constantly starving. He may even put his life in jeopardy for a decent meal every now and then.

Rolly is one of Pongo and Perdita's fifteen puppies. He is the heaviest of the puppies, and is constantly hungry. He is usually heard asking his parents for food, even after being rescued from Jasper and Horace Badun by his parents. When the Dalmatians attempt to disguise themselves by rolling in soot to look like Labradors, Pongo quickly sends Rolly back, as Rolly was only half covered. At the end when the puppies returned home, Rolly was seen yet again asking his mother for dinner.
