In the aforementioned episode, Robin, her parents, and their pet cat, Ginger, had just moved to Townsville next door to the Powerpuff Girls and their dad, Professor Utonium. Bubbles was the first of her sisters to befriend Robin, but Blossom and Buttercup are also good friends with her. The sisters quickly started hanging out with Robin a lot, but soon, their crime fighting agendas left them with no time to actually hang out with her.
Soon, Robin met Princess Morbucks, who tricked Robin into leaving the girls and stealing, but not because she wanted to be friends with Robin, but for her need to be a Powerpuff Girl. After she tricked Robin into stealing candy from a local convenience store, she tattled on her to the authorities and the Powerpuff Girls arrived. However, after everything was explained and the truth was revealed, Robin was pardoned and Princess was arrested. Robin and the part where she was a victim of Princess' conspiracy was referenced in 'Twas the Fight Before Christmas.
It's possible that she may be closest to Bubbles out of the three Powerpuff Girls, since Bubbles was the first of the three to actually befriend her, and whenever Robin's with the sisters, she's usually nearest to Bubbles.
