In front of the entrance for "Living Quarters" it will be walking back and forth. Once it sees you, it will begin to follow you back and forth. Jump up in the air, then land on the crab. It will flip over, also revealing a key. Walk past the crab and the key to pick them up. Hope this helps! :D
You jump on it
well it may or may not be 7

You have to get the robot to drop it on the pipe thing coming out of the ground

Your robot craks it.
There is this robot crab with water in it that you find to the left of main street. when you are back at the burning hatch, crocker (if you have gotten him, if not, go back to the left of main st and figure out hoe to get him) will smile and your poptropican will say, "It looks like he wants to help!" you then go to your inventory and click USE on the robot crab and then the robot crab will be held by crocker. he will drop it onto the hatch and then that enables you to open it!
The robot crab is full of cold water, which you can use to cool down the Hot Hatch at the Hub on Steamworks Island. However, you will need Sprocket the Robot to help you. Find the robot at the Living Quarters to the far left of the main part of the island. Jump on him to get him and Sully's door key. Using the Steam Generator (trash bin at the Cantina), open Sully's door and find Sprocket. Ringing the bell on the counter will awaken him. Take him and the crab to the Hot Hatch at the Hub. Use the robot crab and Sprocket will drop it on the Hatch, cooling it down so you can go underground. That is the only use for the crab.
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.
