"Ernie Coombs hosted this simple format TV show as Mr. Dressup. With his
puppet friends, originally Casey and his dog Finnegan, he taught
pre-school subjects with games, music and simple activities. To add to
the fun, Mr. Dressup would always open up his tickle trunk that contains
any costume for any role he wants."
