The mycelium and plant root do not need to touch to form a connection. If each is fully extended, both teams will earn the bonus.

It is not possible to earn the bonus in remote competitions or if there is no opposing team.

FLLCasts Tip

This mission can be solved by pulling the lever. Another option is to block the lever so it cannot move forward and then lift the Mycelium quickly, causing it to extend.

Watch the chain while lifting the Mycelium because it can catch on the attachment. This approach is easier if the robot comes in from the side of the Humongous Fungus model.
