This can be quite confusing so you’ll need to concentrate. We’re talking about two different kind of slugs here: slugs and mole-slugs.
A slug = a regular slug
A mole-slug = a slug that looks and behaves like a mole
Then you also need to know what a slug-mole is.
A slug-mole = a mole that looks and behaves like a slug.
So a Slug-Mole-Slug is either a
Slug-Mole-Slug
or a
Slug-Mole-Slug
A Slug-Mole-Slug = a slug that looks a behaves like a slug-mole, i.e. it’s a slug that looks and behaves like a mole (that looks and behaves like a slug).
A Slug-Mole-Slug = a mole-slug that looks and behaves like a slug, i.e. it’s a (a slug that looks and behaves like a mole) that looks and behaves like a slug.
Easy.
One day, if you’re lucky, we’ll tell you about Slug-Mole-Slug-Mole-Mole-Rats. Now that gets complicated!
