Mr Pam Pam and his baby are regular visitors to the house of the boy who narrates the story im this read-aloud picture book. Mr Pam Pam is very tall with stringy arms and legs and he says his favourite food is banana ice-cream with gravy. But then Mr Pam Pam says lots of things that you cannot be sure are true. He says, for instance, that he's seen a Hullabazoo with yellow hands and a green moustache, a bouncing, twizzling Hullabazoo. But whenever the boy looks where Mr Pam Pam tells him to, the Hullabazoo has always gone, until one day there is the Hullabazoo, just as Mr Pam Pam described him, wearing purple socks and a flat orange cap with a star on the top. And the small boy is truly amazed. Patricia Aggs has also illustrated "Count Karlstein", "The Sleepy Book", "Florizella and the Wolves", "Florizella and the Giant" and "Why the Sea is Salt".
