Silent Forest

"Deep inside the darkest of woods, Silent Forest offers maze-like caverns, tumbling temples and crocodile-filled swamps to try and stop Sonic the Hedgehog in his path."

- Sonic Lost World Website

Silent Forest is the fifth stage in Sonic Lost World. This level features two variations of the stage; a forest-themed zone and a haunted-castle themed zone.

Zone One
As the name states, Silent Forest is a gigantic forest of sorts. It has some resemblance to previous forest stages, including Jungle Zone from 8-bit version of Sonic the Hedgehog, Tropical Jungle from Sonic the Hedgehog (2006) and Frog Forest/Lost Jungle from Sonic Heroes. However, it also has a large basis on Mushroom Hill Zone, including a new mushroom-based gimmick and featuring a lot of classic enemies from the zone, such as Mushmeanie's, Clucker's and Madmole's. Grind rails are presentable in the level, as well. Sonic can grind on the grind rails, but he must watch out for the upcoming minecarts ahead. The Crimson Wisp and its Color Power, the Crimson Eagle, appear in this act as well as the Black Wisp.

Zone Two
Like the other zones in Sonic Lost World, the Silent Forest has a different act themed level in the zone. The tone of Silent Forest switches into a haunted-themed area, but a forest is seen in the background. The music also changes considerably from jungle-like to tango. This act also features a section for Sonic as a potential ‘stealth’ section in which Sonic has to navigate a zone without being spotted by giant owls and stone pig obstacles. The Magenta Wisp and its Color Power, the Magenta Rhythm, appear in this zone.

Zone 3
As seen from Silent Forest gameplay footage montage, it seems to take place in a frozen cavern, similar to Zone 1 of Frozen Factory or Zone 3 of Windy Hill.

Zone 4
This zone takes plave at an old ruins.

Unknown Zone
As seen in the screenshots and gameplay montages, this act has the same details and design as Wii U Act Two.
