Dolly and Clarissa trib-time

Dolly is optimistic, energetic, and outgoing. Although she may be less responsible and mature than Dylan, she is still trustworthy enough to take care of her 97 younger siblings while Delilah and Doug are away at work each day. Dolly describes her personality as "fearless and feisty" while Dylan snaps back by quipping, "Nah, more chaotic and noisy."

Clarissa is the snooty neighbour of the Dalmatian family and is often seen with her human, Hugo, who gives her anything she wants. She is annoyed by the Dalmatians, especially Dylan and Dolly, the latter of which she has a rivalry with. Arabella and Prunella serve as her sidekicks. Clarissa often refers to herself as "one," as she views herself higher than others.

Both also like to have sex with each other when nobody's around.
