This is actually extremely intriguing.
For the clone test and pet ordeal, I'm pretty sure the pet items are simply Collectibles, and the clone test a developer tool that was tested once, or something. Don't take my word for it, it's an educated guess.
However, the bottom few shop links are extremely interesting. One of them was a Void + Demon pack. Two of the most hardest yet coolest colors to get, and you can get them for about 1 Mil tc in usd. Not to mention they're in packs (no qi properties), so they sell for 2mil/3 mil plus each if they were to sell. If you ever have spare money and you want some no qi stuff, that's the place to look. Haha.
If you find anymore of these, feel free to edit the OP and add them. I'm so surprised I haven't seen those before.
