Beanworld is the nearly three-decades-old fantasy comic by Larry Marder that follows the adventures of minimalistic characters known as Beans. Bean!, meanwhile, is a fantasy role-playing game published by Fabled Worlds in which participants go on adventures as beans (and, from what I can tell, may involve actual beans).
“You’d think in this day & age you might try Googling a name before doing something as stupid as these people have done,” the cartoonist wrote on Twitter. “My lawyer notified. Start the process of dealing with this thief tomorrow.”
Asked later whether it is “just the name, or does the setting in the book have a resemblance to Beanworld cosmology?,” Marder replied, “Source book title is same as my registered trademark Beanworld. Characters look like a smoosh of Mr PotatoHead and CA Raisin.”
