jump on top of it.
You have to jump on it and then you pick it up when it's upside down.
there is no robot that drops the crab! what you do is when you see the crab don't click it, just jump on it then pick it up. sorry but that's all I know.
The crab can be found in the Wimpy Boardwalk Island on Poptropica. The crab will be found on the boardwalk at the end of the mission. The crab can be picked up using the helicopter.
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)
I think its up the monsters butt, love ameister
the way to use the mech is to find all the items needed to activate it and use it as a vehicle on your journey to victory.By the way pick up the attachments and use it to kill plants
You can use the cold water inside the crab to cool the Hot Hatch at the Hub. When you jump on the robot crab at the Living Quarters, you also get Sully's key. Go left and pick up the Old Vine from the roof of the Storeroom, then go to Sully's. Open the door by setting the Steam Battery to -5, and you will find Sprocket the robot. Ring the bell to wake him up. You will need him to drop the robot crab on the hatch.
After you get in Sully's shop,just ring the little bell on the left of the robot:)
try and pick it up. If it pinches you, then there's a good chance that it is not a good crab.

click on it
To pick up the sack of mortar just run over it or click it.
