Creepus explodus, sometimes viewed as the Creeper, is a green, upright quadrupedal fungi. Whenever a Creepus explodus gets excited, it explodes in happiness. When the Creepus explodus explodes it also emits spores (Invisible to the human eye) called Creepus genus that create more Creepus explodus. The babies grow and learn then go out in the wild.
Enderman
Endus movus, sometimes viewed as the Enderman, is a tall, black, biped. It's home (The End) is constantly getting blocks stolen and they feel like they must make a new home, with the new home. They make the home with their block moving abilities and can make complex things with the blocks. Whenever an Endus movus teleports, it emits a purple goo (Invisible to the human eye) called Endus genus, that, as you may have guessed, make new Endus movus.
Fart
Fartus smellus, a greenish gas, comes out of the butt of Jerry, Harry, Potatoe, Saul, and Hai, because it smells, only they can be near it!
For example:
Stem anthro=man
Stem fin=end
Stem trans=move
Stem gen=origin
Enderman=Anthrofin transificus
Enderman Reproductive Spores=Anthrofin genus
See what I mean? It sounds much more scientific and official!
