Cervix Tunnels

Cervix Tunnels are areas within Palm Plants in Sonic Heroes that are accessed via large open holes. They appeared in both of the following stages: Frog Forest and Lost Jungle.

Description
They can usually be entered when the team grabs a floating flower that takes them inside. However, Team Chaotix are unable to access the cervix tunnel in Lost Jungle due to a blocked entrance, so they must find another way to access the area. Inside the tunnel are numerous Glowing Mushrooms.
