Krindlekrax was one of the books featured and appeared alongside such classics as Roald Dahl's Matilda and J.K. Rowling's Harry Potter and the Philosopher's Stone.

It centres around a 9-year-old boy named Ruskin Splinter, who is small and thin with thick glasses, red frizzy hair, knock-knees and a squeaky voice.

Ruskin's special friend is the local school caretaker, Corky Pigeon, who tells him his experiences with the evil monster that lurks in the sewers and terrorises the street, a giant fire breathing crocodile named Krindlekrax.

Suddenly Corky unexpectedly dies, and everyone suspects it to be a heart attack, but Ruskin knows that Krindlekrax was responsible, and is angry with all of Lizard Street for allowing it to happen.
