Lost Jungle is the tenth stage in Sonic Heroes. A watery swamp inside a vast jungle, the level contains black frogs that destroys nearby plant life, in contrast to the green frogs seen in Frog Forest. A giant alligator lives in the lowest point of the swamp.


Descending from Frog Forest's canopy, Team Sonic ventures through the depths of the jungle to stop the Egg Fleet to save the world. Team Dark explores the depths of the jungle to pursue Eggman to make him answer for the Shadow Android. In the final steps of the level, Team Sonic and Team Dark must escape a giant alligator that chomps its way to the team. The player must swing on the ivy swings and jump to another until they land on a ledge. Team Rose must escape the jungle to stop the Egg Fleet and impress Sonic. Team Chaotix are tasked to rescue ten Chao.

  • If Tails is left idle, he will say, "I hate that black frog."
  • A stage in Sonic Lost World, called Silent Forest, has many similarities to Frog Forest, Lost Jungle, and Tropical Jungle, the latter being from Sonic the Hedgehog (2006).
  • The black frogs here do not appear in the previous stage, Frog Forest, despite it being named after frogs.
