Sylvania Castle Zone

Sylvania Castle is a stage/zone that appears in Sonic the Hedgehog 4: Episode II. It's the first stage of the episode and the fifth/sixth of the full game. It is followed by White Park Zone. As the name implies, it is an ancient castle that is full of traps by a lake that has fallen into despair and has flooded through the years. The stage's appearance is a hybrid between Aquatic Ruin Zone from Sonic the Hedgehog 2 and Marble Garden Zone from Sonic the Hedgehog 3. The spinning wheel obstacle from Marble Garden also returns, opening other routes in the stage, as do the arrow-shooting Reliefs. Red and yellow variations of Fullboar appear in this stage, among other badniks such as Chop-Chop and Bubbles.

Trivia

 * The name of this stage is possibly a parody of Castlevania.
 * This stage was thought to be the "reused level" Sega's Ken Balough mentioned before this stage was revealed. However, in recent interviews, he revealed that Sega is bringing back a zone from the Classic Sonic trilogy which connects to the storyline of the game.
 * The level also bears a strong resemblance to Kingdom Valley in Sonic the Hedgehog (2006). Kingdom Valley was often noted as somewhat resembling Aquatic Ruin Zone.
 * As the player progresses from Act 1 to Act 3, the setting of this stage changes from day to night. This is similar to Splash Hill Zone from Episode I where the stage started out as in daylight until the third act which changes to a sunset setting.
 * "Sylvania" literally means "forest land" in Latin. So the stage can also be known as 'Forest Castle Zone'.
