Furball has one of those lifesize, fully featured, orifice equipped, 'play' dolls that sad Americans spend thousands of dollars on because it enables them to bed their ideal woman (who coincidently looks like their mum).
In Furball's case it is actually a lifesize model of Martin Jol, because that is all they had left in the shop. A full size Henry would not fit in his mum's basement. And that wasn't an innuendo.
