The Sign is a pretty good song. I seriously doubt anybody's reading this who doesn't already know, but the movements sync up with The Sign by Ace of Base. If you didn't know, then thanks for being here this far in. I like to think that this hallway and its layout was planned from the beginning specifically for this video.
Petscop 21 is the last of the Easter 2019 episodes, everything starting on Petscop 17 through this one was released on the same day. It was really exciting, I think that Petscop is way better to watch in retrospect since everything's already there, but you won't experience that part with Petscop now.
