Giant frogs

The giant frogs play an important role in the Sonic Heroes levels Frog Forest and Lost Jungle. The frogs have the ability to make it rain, either making plants grow rapidly or destroying them. The green frogs make plants grow and allow the characters to access new areas of the jungle. The black frogs make plants wither and die. The frogs are easily startled, causing them activate their powers. Team Chaotix have to avoid detection from the frogs during their mission, as they are supposedly discovered by Eggman's robots during rain but can avoid detection due to Espio's ability to turn invisible.
