Fluoride as a Cane Toad is pretty much the best comparison I can make as an Australian. Fluoride is highly toxic halogen, and almost everything reacts with it.

Neon is often used in colorful lights by humans, along with other noble gases and colored glass or additives to make them shine a particular color and brightness. This is how for me Budgerigahs fit in with Neon.
