Acrostic - The Curse of the Bogle's Beard

Hello. For the next bit of my homework I created a new name for this book and wrote an acrostic with it. My new title is The Deathly Bog.

The
Horrifically
Exciting adventures of Barnaby.

Dark pickles, are they Barnaby's dad?
Exhilarating and magical.
An imaginary car that runs on vinegar.
The best book I've recently read.
Ho-flay pickles, what are they?
Locked cellar, mysterious.
You will adore this book.

Barnaby, an adventurous boy.
Of course it's good.
Granny Hogsflesh, who is she?
