OMG!! AN IMMORTALITY EGG!!!!
Immortality eggs are believed by some people to be the most powerful eggs in the entirety of the UnUniverse are eggs that kill you, thus the usage of the word "Immortality" or no mortality. They only happen once in a full moon (or basically every month at Arby's).
Lore[]
In the year ⠀⠀⠀⠀, scientists attempted to improve the UnUniverse's most widely-used medical item there is, the classic GNEgg. While observing WellFiredChickens, a scientist noted that a particularly stupid MENTALLY CHALLENGED specimen laid out these weird blue swirly eggs. One evening, he took some of those eggs home and attempted to eat them; he was later found dead that evening.
They have been proven to be ridiculously effective... at doing the opposite of a GNEgg. They could euthanize the sick, catalyze aging (WOW!!) and even plunge the dead into Hell if someone's salty enough to test that theory.
