The "Just In Case" Precautions

Batch 145 is something that I readily admit was a complete and total failure. Most of my creations have something redeeming about them, some quirk of personality or hidden use, some point where I can reach them and connect with them and let them know that even if the world shudders, I will love them as my creation. That is not the case here. While I was able to destroy every last trace of them, save what exists of the DNA formula in my mind, there remains a certain doubt as to the utter eradication of the species.
A/n: There would be significantly less doubt on all of our parts if Ruby would stop messing around with that line of genetics altogether, but no. She has at least promised to never recreate this specific branch, but somehow that doesn't comfort me as much as it would for anyone else.
Hence, the Precautions.
They're all superstitions, of course. No need to complete every single element each time Batch 145 comes up. But still, it's important to be aware of the possibilities and take the time to work a little counter to what can only scientifically be termed as "bad juju."
There is a list. Here you go. Some of these are probably entirely ineffective but those ugly little eldritch nightmares were so horrible that I'm not taking any chances.

1. Spit on the ground
2. Salt over shoulder
3. Spritz air with holy water
4. Sign of cross, particularly if near religious site
5. Clap three times
6. Check any available life signs detectors
7. Spell the word "Dendrobranchiata" backwards
8. Order seafood, consume, cleanse dinnerware in fire
9. Turn up light intensity
10. Make a sign of a pincer with your hands and then bite your fingers
11. Curl up on ground and pray for 14.5 seconds
