(*2*)The indisputable fact that Knuckles first enters the tale at the Mushroom Planet is fully suitable, for the reason that the locale is obviously impressed through the “Sonic & Knuckles” stage Mushroom Hill Zone. Since “Sonic & Knuckles” is the primary sport by which the purple echidna become a playable persona, and because Mushroom Hill Zone is the primary stage of that sport, the degree can simply be observed as Knuckles’ debut — his Inexperienced Hill Zone, if you are going to. As such, it kind of feels extremely intentional that he makes his first look within the “Sonic” movie franchise surrounded through mushrooms.
(*2*)This creation comprises a few different nods to the video video games as neatly. Knuckles being tricked into operating for Dr. Robotnik is a commonplace incidence within the video games, and it is the major plotline of “Sonic the Hedgehog 3,” the place the Knuckles first seemed as an unplayable villain. Even Eggman’s little Mushroom machines may well be observed as intentional references to the “Sonic & Knuckles” stage, which itself featured more than a few levers, elevators, and different units product of mushrooms and vines.
