The pyloric stomach
The pyloric stomach is the crab' stomach and must be removed. Turn the crabshell and push out "the pyloric stomach", which is situated behind the eyes like a bag. Push down until you hear a little click—this means it has come free. The pyloric stomach can now easily be taken out and discarded.
