To explain a muckle, I first need to tell you about mickle. Mickle means large, or great amount. Eg, to keep Patsy happy, provide a mickle of cakes. They can be small cakes as long as there are a lot of them, as many a little makes a mickle.
Got that? OK, now you may have heard that many a mickle makes a muckle. Well it's not entirely true as mickles and muckles are the same thing. So you just need one mickle to make a muckle, as long as it's a big un - which it will be as mickles are large.
Compared with a ping pong ball, The Sphere is a muckle beast. Or perhaps mickle suits him better?
