Simlish was intentionally designed to be linguistically neutral, so we didn't have to laboriously translate all the game audio into dozens of languages.

For the same reason, botanical nomenclature should obviously be standardized in Simlish. Sul sul, Laganaphyllis simnovorii!

Laganaphyllis simnovorii is the scientific name of the Cowplant, literally suggestive of a plant that devours Sims. It first appeared under that name in The Sims 2: University as a Natural Science career reward. The Sims 3 Store also uses the full name officially.

>This bizarre bovine vegetation is large enough to swallow your next-door neighbor whole. In fact, it WILL eat your neighbors. Your friends will be hard-pressed to resist the tantalizing vine-cake of the carnivorous Laganaphyllis Simnovorii. After it has consumed some prey, milk it for sweet, rejuvenating nectar of life. A swig of this liquid refreshment will add precious days to a Sim's life and wash away any regret they may have over their visitor's fate.
