CourtneyB,
Have you tried the Ricky Ricotta's Mighty Robot series? It is a chapter book but has only a few sentences per page, has a picture on every page, and has a cool flip-o-rama section in every book. Each book involves Ricky (a mouse) and his best friend (a giant, good-hearted robot that Ricky meets in the first book) battling a different evil guy from a different planet trying to take over earth (a totally silly evil guy). The "confrontations" in the flip-o-rama sections are mostly foot-stomping and head-bopping, although there is an occasional punch (I hate violence in books, but this is really tame cartoon stuff). There is very little tension in the books and they mostly are just good clean fun. Both my boys loved them and were a good gateway to chapter books without a ton of words.
