Giant Porcupine and Agile Maneuvers Feat?

Anyone have a guess on why the Giant Porcupine (Bestiary 3) has a feat that makes them weaker? The creature has a 17 Strength and a 12 Dexterity and the Agile Maneuvers feat baseline.

The benefit of the feat, which turns out to be a penalty for the porcupine, is that the creature's Combat Maneuver Bonus is calculated by adding Dexterity (instead of Strength) when determining its CMB.

Do you think this was just a basic oversight during the creation process? Seems odd to assign a feat to a creature that makes it weaker.

Oversight seems like the reason, yes.

It might be that an early version had the STR/DEX scores switched, but at some point in development it was decided that it should be strong rather than agile, and noone remembered to change the feat.

Maybe as a nerf to make its combat maneuvers less effective despite having a high strength score?

Possibly, but I'd probably just have assigned an arbitrary 'weakness' rather than spending a feat.

If you decide it's an error and want to substitute a different feat, use Iron Will. Ever tried to get a porcupine to do something it didn't wanna? Yeah, me either.

That's because they're a bunch of pricks rolled into one.
