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 game. As the name implies, it is an ancient castle 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. 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 a parody of Castlevania.
 * The level also bears a strong resemblance to Kingdom Valley in Sonic the Hedgehog (2006).
 * Later in the stage, it turns a night time setting. This is similar to Splash Hill Zone from Episode I where the third act changes to a sunset setting.
