Jeb is the very popular rainbow sheep. Here are two interesting facts I have learned by owning Jeb: 1. If you have two Jebs and breed them, they won't make a rainbow baby. It will just be a normal sheep. 2. When you shear Jeb, you get a normal color of wool. (black, gray, dark gray, brown, white) When I shear one of my Jebs, I get white wool. With the other, I get brown. The exotic colors (like red, orange, pink, yellow, blue, purple, lime, etc.) are made through dyes and such. I think that before Jeb is traded to someone, these two facts should be conveyed. That way the purchaser knows what they are buying.
Before buying rainbow sheep, there are another 2 things to know: 1. buying 2 sheep eggs are 10 grass, it costs 5 enchant points each egg to rename them jeb_ 2. anvils can name many rainbow sheep eggs, so dont spend 20 grass on 1 rainbow sheep. That 20 grass should be put towards buying an anvil or something useful. only spend 5 grass-7 grass on the egg. You have been warned
