(fee-tuh-chew) n. The Pokemon characters (there are multiple ones) that are fetus's. They have the Umbilical Whip, the Amnion Slap, and if the going gets rough they can Abort Mission using his
Rusty Coat Hanger.
When the Fetachu are in herds, they are called Feti.
One Fetachu has 40 hit points, a moderate character. But when multiples of Fetachu are in play they work as one character and the hit points are
calculated by adding the 40 times however many are being played and then multiplying that number by two. For example, 3 Fetachu's being played would be: 40 x 3 = 120, 120 x 2 = 240. The total hit points for three Fetachu are 240. This makes herds very valuable.
(all seen here is the work of a
friend of mine, except i made up the umbilical whip and the hit points)
