Any tips for getting sh****y chalk off the wall

And yes, it's exactly how it sounds. Dc2 ate chalk yesterday, shat it out today, and in a dirty protest for being putting to bed proceeded to smear chalky crap all over the walls and himself. So now the wall is a lovely shade of purple. Repaint or any magic tips?

It's grim. The smell of soapy warm poo makes my stomach turn 😂 was furious after he had a lovely warm bath and I had to shower him again! Boys are gross!
