It's a fake baboons bottom. Part of a story.
It's also a giant dildo and fake breasts with big nipples, being shoved in the faces of passing women.
And if that's what they did in the street, god knows what they did in the library.
Apart from the simulated sex with each other that you can see on the video before they ran outside.
Still, as the library says, "if you've got it, flaunt it" and to hell with anyone who doesn't want to see it but is rude enough to look (because they can't fucking avoid it).
I'd say I'd be amazed if all that was part of the children's picture book, but these days who knows what they think is appropriate for KS1 kids to look at.
