Claim: In La frousse aux trousses, Spirou and Fantasio never tried to travel to Touboutt-Chan but the two journalists have trouble finding the funds until a man funded the trip.
Evidence: La frousse aux trousses, written by Tome and drawn by Janry, is the fortieth album of the Spirou et Fantasio series, and the eighth of the authors. In La frousse aux trousses, Spirou and Fantasio intend to make a journey to Touboutt-Chan in order to clarify the fate of Adrien Maginot and Günter Siegfried, who disappeared in the 1930s while seeking a mythical place in this area of the world, the Valley of the Outlaws. However the two journalists have trouble finding the funds necessary to the achievement of their project. They are then contacted by Doctor Placebo, who is persuaded that frightening experiences are a sure-fire cure for hiccups. He offers the two heroes funding for the trip, on condition that they take along the patients sent to them by the doctor, in the hope that their experiences will prove his theory.
