It's a swamp, so be careful.

Rouge the Bat, Sonic Heroes

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 and 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 is tasked to rescue ten Chao.

Team Chaotix mission

For this assignment, Team Chaotix is ordered by their client to protect and collect Chao. The normal mission requires them to collect ten Chao, while the extra mission requires that all twenty Chao in the stage are collected. The location of each Chao are as follows:

Chao #10 The player should let the green frog from the previous section see them. When the vines and platforms grow out, the player must fly up to get the Chao flying on the growing platform. Tsonic win 2016-08-29 17-15-16-502.png
Chao #11 After going up from the previous section to another circular path, the player must destroy the Solid Flapper near the locked Case to release the Chao inside. Tsonic win 2016-08-29 13-40-53-392.png

Chao #15 From the fourteenth Chao, the player must fly down to the bottom of the path where they will see an Egg Hammer. They must destroy it to release the Chao in the nearby Case. Tsonic win 2016-08-29 13-42-43-008.png
Chao #16 From the previous Chao, the player should not go through the laser field. Instead, they must continue on the path from Chao #15 to the Special Key. The next Chao can be found behind the Special Key near a mushroom. Tsonic win 2016-08-29 13-42-47-691.png
Chao #17 From the previous Chao, the player must return to the laser field and pass through it by turning invisible. They should then use the Warp Flower inside to reach a ledge on top and destroy the two Solid Flappers to release the green frog. After the frog sees the characters and it begins to rain, the player must go to the right and bounce up from the fruit to get the next Chao. Tsonic win 2016-08-29 21-07-30-925.png
Chao #18 On the left side of the same section with the seventeenth Chao, after the frog sees the characters, the player must jump up from the newly grown platform to get another Chao. Tsonic win 2016-08-29 21-07-43-408.png
Chao #19 The player must bounce off the spring that the green frog was on to the platform above. They should swing from the ivy and destroy the Solid Flapper, then collect the Chao from the Case. Tsonic win 2016-08-29 13-44-08-791.png
