four pretty fun adventure stories. same slightly flimsy plots, clunky storytelling and frankly weird artwork, but the scope has got a lot bigger, the format a bit less rigid, and some of the frames are sophisticated enough they almost seem to have been ported back from later books (the style of Jijé's underwater scenes in Spirou et les hommes-grenouilles in particular is very reminiscent of Franquin's Spirou et les hommes-bulles from almost a decade later). the flipped text in Comme une mouche au plafond was another clever touch.
