You found out the secret!
They are not Gremlins though.. they are actually ZapNanobots.
I revealed my plans for this long ago, but my error at the time was to have the nanobots planted in the actual Zap units.
When Rick invented the ceramic RockZap, the Solid Stainless Steel Heat Port combined with it's external ceramic sleeve left precious little room for my Nanobots, that complained relentlessly about the warmth down in the bowels of the Zap.
I have recreated these guys, in a smaller version, and they are planted in the actual Zap Stem screens!
Tjhey are extremely small, and the herbal system they use incorporates a new technology that incorporates auto feminized Super short flowering time auto-flwer dwarf plants that the nanobots recycle as we sleep... eat... and even hit the stems. Using an electron microscope, I was able to get this video footage of the guys at work~
