Alternate costume: At the eighth area (CGDM password), go up, then
right, then up. Wait for the Grogg to kill the human. If he does
not, you must start again. Go to the right edge and wait for the
Grogg to go to the edge. When he does, go to the next screen and
he will appear. Kill the traitor. Jump over to where the traitor
used to be then jump up and press Up. After the Grogg shoots
twice you should change colors. If not, just kill him and it should
work.
