Sylvania Castle Zone is the first level in Sonic the Hedgehog 4: Episode II. Following the events of Episode I, Sonic and Tails arrive here on the Tornado. It shares many characteristics of Aquatic Ruin Zone from Sonic the Hedgehog 2 and Marble Garden Zone from Sonic the Hedgehog 3 and is home to new badniks such as Fullboar and Zoomer.
Each of the three acts serve to teach the player(s) how to use each of the Tag Actions in the game. Act 1 introduces the Copter Combo, Act 2 introduces the Submarine Combo, and Act 3 introduces the Rolling Combo. In a new game, the player(s) cannot use these actions until they reach the first instance in which they are required.
||In the deep forest, an old castle is located by the lake. Despite its magical appearance, traps like floating pillars, made to protect the castle, will await the duo.
