Having trouble explaining what you do for a living to your kid? Let Stocktopus help. Part broker, part purple octopus, Stocktopus is one of five animated characters from an educational CD-ROM called Thinkin' Things Collection 3. The game helps guide children as they trade objects (apples, basketballs, TVs, soda cans). If Johnny struggles with a deal, he can click on the “help” button and Stocktopus will recommend an appropriate choice. (Good thing your clients don't have one of those buttons.)
