Big Bird's earliest animated appearances were cameos in cartoon segments. In the early 1970s, a cartoon version of the Bird spoke in a short "Mystery Drawing" segment; when the picture of Big Bird was revealed, he said, "It's me, you sillies!" He also appeared in the animated insert "The Noble Ostrich," as designed by Bruce Cayard.
Big Bird's most substantial animated appearance to date occurred in Follow That Bird. The cartoon Big Bird first appears blowing up the Warner Bros. logo, explaining that "Sesame Street is brought to you today by the letters W and B." A later animated scene has Big Bird imagining himself surrounded by a Bird Family, all of whom resemble him. These cartoon scenes were supplied by the Toronto-based Animation House Limited.
