Following in the hugely successful hoofprints of Boris and Dudley, Sid is a monster who fancies himself as a big scary finger-nibbler. Readers are advised to sit on their hands while Sid is on the rampage, but then it's suggested that perhaps Sid isn't as scary as he'd like to think? Readers are encouraged to roar loudly back at Sid, who is reduced to a quivering wreck by the turn-around, quakes with terror and runs home crying, where he gets his favourite tea - FISH fingers! Lots of opportunities for interaction with the reader and child who is being read to, with questions and suggestions made in the text.
