Preposterous just lies around and doesn't do anything; he doesn't like to bark or play. Sometimes he would even attack Oscar.
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."
