A shoe shine puppy who always talks in rhymes
transforms himself into a superhero every time Sweet Polly Purebread
(a pretty TV reporter) gets in trouble.
Did you know... The episode "Simon
Says, 'No Thanksgiving'!" is unique in that it marks the one
time that Underdog does not speak in a rhyme when he says "Not
plane nor bird nor even frog. It's not even little old me, Underdog.
It's a balloon."
