"Zero points"! This is the note that Roméo Mécano has received today at school for not having been able to recite his poetry in front of the class. It is certain, Roméo is not a poet, he is even rather of the kind resentful. He will demonstrate it again tonight by building a gigantic robot stuffed with innumerable gadgets intended to demolish his school! Fortunately, the Pyjamasques are there to try to prevent him from carrying out his project!
