Animated object stat block

[Arden Oakwald]

Can someone help me figure out how a Diminutive animated object's stat block should look?

The listing only goes down to Tiny, which has 1HD, so I don't know how to drop it down another size x_x

Apply the young creature template?

It can't go below 1HD. So, just drop the size and apply all relevant modifiers from the new size.
