Wales and Scotland aren't actually in Hetalia yet, but the personalities are generally accepted as being England's older brothers that like to pick on him. <3 You should totally get into it.

Aahahaha yes. Well. There are a lot of sheep in Wales. No, like, 2 sheep for ever 1 person. And so comes the old joke that Welsh people love their sheep a little too much and... the rest is history. Or rather, very old jokes: "What do you call a sheep tied to a lamp post in Wales?" "A leisure centre!"
