According to its map, the park contained at least the Spacey Zoomer Ride, a beach, a "water world", a "big wheel", a garden, a boating lake, a port, a hotel, "Fireball", "the Giant's Cauldron", "Eyeball Terror", "Mushroom Terror" and "Natty Longshoe's Comical Castle". (TV: Nightmare in Silver)
A platoon, led by Captain Alice Ferrin, was sent to Hedgewick's World as punishment for their disobedience. The day that the Eleventh Doctor, Clara Oswald, Angie Maitland and Artie Maitland arrived there, a newly-upgraded race of Cybermen invaded. When the army of Cybermen became impossible to eradicate through direct combat, the planet was destroyed under the orders of Porridge, the chess-playing dwarf, who was the Emperor in disguise. Through voice-command, he armed a bomb to implode the planet housing Hedgewick's World of Wonders. This act wiped out nearly all of the Cybermen, but at least one Cybermite survived the planet-wide destruction and persisted in outer space. (TV: Nightmare in Silver)
