The dunk

“Noooo!” I cried. “Digestive’s been dunked!”
Oh, I’m choco and my friend has been dunked. I cannot believe it. My friend was turned crumbly. I wish I could help however, I am scared of the dunk. I must help. But I can’t. But I must.
“Ahh!” A voice screamed. It was Custy! OK, that’s it. I must do it. And next thing, I knew, I was surrounded by Twinnings.
“You saved us!” Thanked Custy. I did. I conquered the dunk!
