Roald Dahl 
Penillion Ach-A-Fi [PDF ebook] 

A collection of (mainly) grisly beasts out for human blood, ranging from Crocky-Wock the crocodile to Sting-A-Ling the scorpion. Described in verse with all Dahl»s usual gusto and illustrated in a suitably wicked style by Quentin Blake. WARNING! This book contains wickedly funny verse, prickly surprises and the most despicable creatures you could ever hope (not) to meet.
