Shabti - Human Disguise Question

[Levism84]

Looking over the Shabti (http://www.d20pfsrd.com/races/other-races/more-races/advanced-races-11-20-rp/shabti) race, is says they "typically look like idealized humans with perfect physiques and flawless features." However, there is no mechanical indication as to whether or not they look like humans or could pass for a human without taking penalties to their disguise check. I was wondering if anyone has any insights about whether or not they could pass for human without penalty, or if they would take the normal penalties for trying to disguise themselves as members of a different race.

Also, would it be reasonable for shabti characters be eligible for the Pass for Human (http://www.d20pfsrd.com/feats/general-feats/pass-for-human) feat? How about the "Mostly Human" alternative racial trait most native outsiders gain access to?

Not familiar with them, but if they need to disguise themselves as the race they are modeled after, they aren't very good facisimiles, are they? Did Baron Von Fearofmortality just hire the cheapest mages he could?

I would say as a planar traveller with literally no human heritage (made, not born) the feat could go both ways. They're born of humanity, just...Not in the biological sense.
