Jetta's Tall Tale Clifford the Big Red Dog : Season 1 Episode 69

Jetta feels a twinge of jealousy when the other children make a fuss over mily Elizabeth's wonderful big pet Clifford, so she blurts out a story about her own wonderful big pet – a huge parrot named Lulu. But the little lie quickly grows into a big mess, forcing Jetta to dress Clifford up as a bird to keep the lie from being exposed. Her conscience finally makes her do the right thing and she apologizes for having created the lie in the first place.
