Epic phails are a subspecies of piffles puffles who are always doing something n00bish and liek mudkipz. They are to be avoided at all times unless you want them to be extinct (like the rest of us).
Background[]
Not much is known about them, but there are many rumours about how they came into being.
One claims that they were made by Flying Bathtubs from Mars.
Another says that they are clones of the evil Bananaphone, who is a deformed Candypear.
