The strip revolves around a yellow
bull terrier named Grimm (aka Grimmy), owned by an anthropomorphic goose named Mother Goose, along with a dimwitted
Boston terrier named Ralph and a
cat named Attila. The strip is noted for its references to popular culture or recent news that are often spoofed and referenced for a certain period of time, depending on the length of the hype devoted to a certain news story or topic, e.g. Grimm's creation of a website known as "GrimmyLeaks", which was devoted to publishing rumors relating to fellow comic strip characters, in reference to the controversy surrounding the scandalous website
WikiLeaks. The comic strip also makes multiple references to iconic fictional characters including
Mr. Potato Head,
Superman,
Batman, and more, along with popular products including Amazon Kindles. The strip also often consists of stand-alone one-panel comics that do not relate to the continuing story or characters. The comic strip is named after the
nursery rhyme collection
Mother Goose and the
fairytale collection
Brothers Grimm. ==Other characters==
