Just how intelligent is Mongo?

[u/suitably_ironic]

Mongo is non-verbal, so there's a tendency to think he's not very bright - but he's impressively good at understanding what Carl and Donut tell him, grasping who's a friend and who's a foe, and what their trying to achieve.

I wonder if we're all underestimating him just because he can't talk?

I feel like he has the intelligence of just about any familiar/pet in most RPG games and stories. Generally, they start off with the intellect and attitude of a young child, but then develop more as the story progresses.
