What's a curly wurly? You deprived person. A curly wurly is the most delicious thing on this planet, besides hersheys cookies and cream (can't wait to go to america next year, I WILL be stocking up). A curly wurly is like this curly piece og caramel with chocolate around it that's for kids n it's great cos they only cost 15p!! It's curly in kinda ladder shape. Difficult to explain, but addicted once you try them!!
