1.) I know you can get them through a Potion of Purity for normal pet scribbles, but what about experiments? 2.) Do they have to be zapped scribble, or can they be turned with a Potion of Purity like the others? 3.) Can you get normal pet scribbles from the zapper and not just the Potion of Purity?

(I separated them so that they could be easily understood, please ping me)

Yes, you use Potions of Purity to get Scribble Experiments, same as any other pet. And yes, I believe the zappers can do scribble for any kind of pet, experiment or otherwise.

Thanks very much!
