Horrid Henry's stinkbomb

Four complete stories enhanced by Miranda Richardson's manic reading and really horrid music and sound effects: Horrid Henry makes a stinkbomb that becomes a weapon in a deadly intrigue between two double agents (Perfect Peter and Moody Margaret), creates chaos in his team project (to build the Parthenon), accepts an invitation to a sleepover from the new kid at school, and acquires a new pet - a tarantula, of course.
