A CBeebies show about a girl who lives in a big pink dome-like structure which has a helter skelter slide around it. She has a bunch of friends who she likes to hang out with and she has hair which looks like Lil Pump's dreadlocks.
Other characters:
Raggles is a blue talking plushie which is meant to be a rabbit, who has a huge head and sounds like Perfect Peter from Horrid Henry.
Holly is a girl younger than Rosie who has yellow hair tied in pigtails and she wears an enormous bow which she never ever takes off.
Will is literally the Caillou of the show. He is very whiny and bossy, accuses people of things they didn't do, and hurts people's feelings all the time. However what makes him worse than Caillou is that Will never ever gets punished for his actions, and his hair looks like bacon strips.
Bluebird is just as bad as Will. She looks like a knock off of Zazu (if you've watched Disney's The Lion King, you'll know EXACTLY who I'm on about) and she bosses people about, refuses to use manners, physically and emotionally hurts Teal and Manny without getting punished, and acts childish over everything.
Big Bear is a big bear, duh. He wears a big orange jumper all the time and if you look under his sleeves, his hands are actually just floating. Creepy right?
Oakley is an oak tree, except he has a face with prickly eyebrows and a nose which looks like an egg plant was stuck to his face.
Archie is a chameleon and he's like the cutest character ever <3
