Foamy is a very cynical and bitter individual. He regularly rants about the fallacies of everyday matters, and treats his acquaintances, including his owner, Germaine, poorly. His interactions with Germaine, for example, usually revolve around him criticizing her lifestyle choices and using her to help with his chores such as buying cream cheese and entertaining his friends. However, Foamy seems to genuinely care about people, as many of his rants focus upon the lack of courtesy and kindness between people. For example, in Foamy: Hurricane Special, Foamy laments at peoples' responses to Hurricane Katrina's wreckage of New Orleans, and insists that people should try to help those in need.
