good APs and modules where the villain is NOT a [bipedal intelligent bad guy]

[Mazym]

I have several PFS scenarios, independent modules, and three APs (Serpent's Skull, Carrion Crown, Rise of the Rune Lords). In only a couple cases, the big problem the players need to stop is NOT a bipedal intelligent bad guy (one is a set of three BIBGs and a big blob, the other is an aboleth). Otherwise it's a BIBG.

BIBGs include anything that more or less has a bipedal "person" shape and is intelligent. I realize this is an imprecise classification.

What are some good APs, modules, or PFS scenarios that DON'T have the main rival be a BIBG?

Spoiler tags may make sense here...

Spoiler:

Serpent's Skull does have a last minute appearance by Ysiderius, who probably doesn't count as a BIBG, but he only shows at the end as a terrible surprise and doesn't run the show.

And I am guessing Dragon's Demand's big foe is the dragon, based on reviews.

Thanks.

Spoilers?:

Dragon's Demand
Thornkeep: The Enigma Vaults
Blood of Dragonscar (if I remember right)
I would definitely count Serpent's Skull
We Be Goblins! (though humanoid, hardly intelligent :)

Wrath of the Righteous:

Deskari, Demon Lord of Locusts

Iron Gods:

Unity, a divine-ascended alien artificial intelligence

Shattered Star:

The Clockwork Reliquary of First King Xin

Carrion Hill:

a Spawn of Yog-Sothoth, akin to the one from the short story The Dunwich Horror

Adventure paths:

Curse of the Crimson Throne:

Although really the final "boss" is Queen Ileaosa, the influence of the immortal but disembodied Kazavon is ultimately what propels her to power. After she is slain, Kazavon rises from the pool in 10 rounds if he is not stopped before then.

Modules:

Doom Comes to Dustpawn:

The Emissary from Beyond (vespergaunt)

From Shore to Sea:

Two bad guys: Gerlach, a gillman turned skum sorcerer being manipulated/controlled by Mohl'omog, an aboleth

The Harrowing:

Zazzrion, the Patchwork Lord, male adult blue dragon

Tomb of the Iron Medusa:

Susandra, female half-fiend medusa cleric 11 (has a lower snake half body, technically only a guardian but she's the final threat you have to collect the prize from the tomb)

Thanks for all the good examples!

Oh, can't believe I forgot this classic (if you don't mind converting from 3.5)

Hollow's Last Hope:

Hollow's Last Hope has no central BBEG (as it's about collecting ingredients for an alchemical cure to a plague), but there's a nonhumanoid relatively big and bad monster at the end in the form of a worg with two levels in warrior named Graypelt. You need to get passt him to get the iron bloom mushrooms needed for the cure. The module is also notable in that most of its foes are not humanoid.
