So yeah, 3 minutes of portal 2, even split into segments, was a little much for Anthology II. Here they are in full. This took one long week of lip syncing to make. Go here for the Pinkie Space segments from the first Anthology.

Don't worry that it's not on my channel. I gave peppermintbiscuit permission to upload it a while back. It's in much better quality than the popular one so go check it out if that matters to you.
