(fee-ta-chew) The Pokemon character that is a fetus. He has the Umbilical Whip, the Amnion Slap, and if the going gets rough he can Abort Mission using his Rusty Coat Hanger.

There are in fact more than one Fetachu, and when in herds, they are called Feti.

(all seen here is the work of a boy named Matt, except I made up the umbilical whip)
1) FETACHU! USE YOUR UMBILICAL WHIP!
2) FETACHU! USE YOUR AMNION SLAP!
3) A wild pack of Feti demolished the town, before killing the women the Feti would jump into their uterus to gain strength.

(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.
