Even if a prospective weaponsmith does manage to get a Slorp sample, which would involve a probably-unsanctioned form of timestream-crossing, throwing it onto a Sue or otherwise using it to destroy a Sue would just give the Slorpling more biomass.

Slorp is made of Sue-flesh. Slorp is capable of subsuming other creatures and gaining their abilities. Those two points, when combined, would make a Slorp-weapon a bigger danger to the continuum than the Sue would have been by herself. At least a Sue usually won't run around devouring anything in its path. And gods help us if the Slorp-copy starts subsuming canon characters!

So, yeah. Slorp-launching weapons=Bad Idea.

I'm pretty sure that if they weren't so sure that they were going to get mauled by other agents those conspiracy theorists would imply that a lot of the PPC's past emergencies were Flower conspiracies.

Okay, some of them could have involved Flowers, but that doesn't mean all of them were in on it. Right? Riiiiiight?
