EARTH MOBILES, AS EXPLAINED BY PROFESSOR XARGLE

Moving right along, the fuzzy, green three-eyed alien who explained human babies so hilariously in Earthlets (1989), as well as our cats and dogs in later efforts, takes up the subject of terrestrial transportation before his class dons their disguises for a field trip to sample the marvels he has described. The professor's comical misconceptions cover several modes of transport, so that only a few pages are available for each; there's less opportunity to expand on the jokes, but the alien nomenclature and literal-minded observations are still amusing. Ross's gleefully satirical illustrations extend the humor in their usual style. Not as amusing as its predecessors, but still good fun. (Picture book. 4-9)
