How does ectobiology work?

You have Appearifying Equipment with which to look back through the Timeline at various things, and warp them to your present moment. However, if you’re trying to warp something that still has a purpose, it would create a Paradox, a Doomed Timeline, and as such it can not be allowed to happen. To prevent this, if the machine detects taking an item would cause a Paradox, it will instead materialize a ‘ghost imprint’ of that object as a mass of green sludge.

If the thing you try to appearify, however, is alive, the Paradox Slime will contain the Genetic Sequence, which can then be manipulated, spliced, and mixed together with other DNA samples from Paradox Slime. This can be used to make genetic offspring as seen during the Credits, as well as to create bizarre mutant things like wiht Roxy’s kittens.

Occasionally, though, it can be used to create Paradox Clones. Both the Ectobiology to create themselves and the Frog Breeding require this. A Paradox Clone is a perfect genetic copy of someone, that will, at some point, be sent to the past and become said person. The Frogs in Jade’s Land were there in the first place, because they were created by Jade as clones from themselves, and sent back in time, which may be, I just realized, precisely what Time Players are required for in a Session. Paradox Clones will, as such, create a self-fulfilling loop- The Kids play the Game because they were created in it and need to play it to Exist, the Frogs are in Jade’s Land to be bred and make Billious Slick, because she went out of her way to Make them one by one, and so on.
