I Can't Believe & The Kindergarten Kids' original release of Robot Girls Z had a Crabstick sub track included as a joke. Of course they only did the first three episodes while HorribleSubs did the rest. Whoever did the Blu-Ray version of RGZ used I Can't Believe & The Kindergarten Kids and HorribleSubs as the source but they left out the crabsticks. If you have MD's Blu-Ray rip of the show and want to watch the crabsticks I ripped them with MKVCleaver. Just add them to the first episode with MKVToolNix or a program of the sort and you're good to go.
The link for the subs file is here:

If you can't figure out how to add the subs file or can't I can upload the video file with the subs merged on request.
