The Mech Walker is the key to entering the storeroom and defeating the monster plants that are active there. Once you finish the Mech with the Motor and Crank, you can attach the Weed Whacker attachment and enter the door at the far left of the island.
in your bag there is a mech crank in it
find the mech crank and mech battery
You have to get the mech crank and the motor.
You can get the mech crank at living quarters in Zack's room ( go up the ladder and exit the room and walk across the vine and pick up the mech crank)
You need to get the mech steam motor and the mech crank. In a garage by Sullys is unfinished mech. Use your two mech items besides it and you then have built the mech.
After building the mech (get the motor and crank), climb aboard the Mech and select Equip on the Weed Whacker on your items. To use the Weed Whacker to "splat" plants, aim up or down with your mouse and press the spacebar.
You will need the Weed Whacker from the secret closet in the Captain's Quarters of the Hub, and you will attach it to the completed Mech (next to Sully's) to use it. The mech motor is in the production zone (far right) along with the key to the Living Quarters, which you need to get the Mech Crank (far upper left at the storeroom). (see related question - this is most of the island)
The unfinished Mech that Zack was working on is in the garage next to Sully's. You need the Mech Motor and Mech Crank to finish it.In the garage next to sully's shop on the left side of the island.
The Mech Crank and the Mech steam motor are needed to complete the Mech walker that is in the garage next to Sully's. It was being rebuilt by Zack. The Mech motor is at the far right in the production zone. (Farther up is the Living Quarters key, in a closet behind the monster plant.) You will need the dirty beaker from the Museum and the Rubber Mallet from Sully's trash box. Once you have the motor and the Living Quarters key, get the Mech crank from the vines above and left of the Living Quarters, and you can rebuild the Mech. Its Weed Wacker is the only way to enter the storage rooms at the far left.
It's at the far left side on the top platform.
