Toward the end of its existence as a zoo, it had a wide variety of animals, including trained lions, bears of several different species, llamas, a gorilla, elephants, monkeys, and many kinds of birds. With declining finances in the 1980s, the park added features to add family interest. After an unsuccessful association with outside investors, Provencher filed Chapter 11 bankruptcy in 1985. In 1987, he changed it to an amusement park, whose full name was "New England's Playworld Amusement Park and Zoo", notable for a huge statue of Mighty Mouse. This change failed to stem the decline, and the park went out of business at the end of the 1987 season.
