Sylvania Castle Zone

Sylvania Castle is a zone that appears in Sonic the Hedgehog 4: Episode II. It's the first stage of the episode and the 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 may be a shortening of Transylvania. Also, "Sylvania" literally means "forest land" in Latin, as the ruined castle is surrounded by a dense forest. Because of this, the stage can also be called 'Forest Castle Zone'.
 * 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.
 * It is noted that Act 2's music contains nods to Aquatic Ruin Zone as well as Sonic & Knuckles' Flying Battery Zone.
 * Act 3's Music sounds similar to the Shop Menu in Sonic & Sega All-Stars Racing.
 * Also, in act 3 The Death Egg MK.II can be seen in the background.
