Snooper and Blabber ran into ghosts and a witch but the scariest characters they encountered were the J. Evil Scientist family.
They appeared in four Snooper cartoons (and, later, in one Snagglepuss). The first was “Big Diaper Caper” (1959). Carlo Vinci’s the animator on it, and here’s one of his two-drawing fear takes (pardon the digital pixilation).
Snooper then dashes out of the scene. He does one of those stretch-dive exits that Carlo drew all the time back then. Carlo occasionally made drawings that would have been at home in a Mighty Mouse cartoon; Vinci spent almost 20 years at Terrytoons. The first one below is a good example.
J. Evil Scientist wasn’t really an evil scientist at all. He never concocted or experimented at all, though he had test tubes and creepy ingredients in his home. He and his wife liked the macabre (they were inspired by Charles Addams’ family, after all) but Junior was the one who did the scary stuff. So it’s appropriate that we salute him on this Hallowe’en.
