Preposterous just lies around and doesn't do anything; he doesn't like to bark or play. Sometimes he would even attack Oscar. He's often seen chewing on a rubber pickle squeak toy.
The dog also made background appearances in Follow That Bird and The Adventures of Elmo in Grouchland, and the View-Master Interactive Vision video Let's Play School, as a pet of one of the Grouchketeers and named Junkyard. The puppet was later modified into Oscar's pet cat, Fido, in "Elmo's World: Cats."
