this is good luck how?

I am working at my friend's store and there is this figurine on the counter that has been transfixing me all day.
It is a Goebel, so the figure looks like a Hummel, but not so terrifying.
It is a chimney sweep.
He has a ladder over one shoulder, a rope over the other and a big pocketwatch/clock in his hand.
And he is riding a pig.

yes...

Andrew swears it is good luck, but i can't get past whether the sweep is really wee or the pig is enormous.

Riding on his pig,

the lucky chimney sweep boy

rides into battle.
