Increasing Construct HD and Beget Bogun

[Felix]

Since it came out in Masters of the Wild, I've loved the spell Beget Bogun. It's the hipper, all-natural-ingredient homonculous. It also has 2 HD and 11hp in the updated version in Complete Divine.

I know I've seen rules pertaining to increasing the HD of constructs somewhere, but a quick search yielded me nada. Does anyone know where I can find those rules so when my druid walks around town he can be accompanied by his 8 HD vegitable man?

Thanks...

Pfew! 2000gp for each additional HD? Criminy.
