Studiopolis

Studiopolis also known as Studiopolis Zone is one of the zones in Sonic Mania and Sonic Mania Plus, but can also be seen in the opening of Sonic Mania. It is a big city full of skyscrapers, billboards, advertisements and more, for example theater objects, trailers, director chairs and giant clapperboards

Sonic Mania
In Sonic Mania, Sonic, Tails and Knuckles jump straight in from a manhole. The three continue their mission to stop Dr. Robotnik and his powerful gem. Whilst doing so, they come across the Hard Boiled Heavies, most notably the Heavy Gunner, who attack the team. Luckily, the heroes defeated the Egg-Robo's and race off.

Robotnik has been found, but escapes after being knocked down by Sonic's group. A news feed flashes, announcing the arrival of a blimp flying over the zone. Sonic and his friends dash and grab on to the "Flying Battery" before it starts leaving.

Sonic Mania's Opening
In the opening of the game, Sonic goes through a giant ring portal and looks at the view of Studiopolis. Suddenly, the Heavy Gunner tries to shoot him brutally, but Sonic evades the Egg-Robo's attacks. With one mighty finish, Sonic blows him up and jumps out of the same portal.

Sonic Mania Plus
In Encore Mode, Sonic and his friends (now including Mighty and Ray) once again pop up from a tube connected from the Chemical Plant and try to retrieve the Phantom Ruby out of Robotnik's hands. But the Hard Boiled Heavies, outside a film studio, attack the other squad, but yet again miserably fail.

Sonic and Co. find the Eggman in a film studio later on and defeat the evil doctor, but a news flash announces the arrival of a blimp heading over the city. Sonic and the rest grab on to said blimp, traveling to Flying Battery Zone.
