I thought about what could be added to the wiki pages, so here I go.
Po is one of the only two tubbybots to leap at the player, the other being Prototype Tinky-Winky. (and vice-versa)
Po, Laa-Laa, Prototype Dipsy, PTLD-93, The Original (although, he never had a suit for the lower jaw to begin with) and the Laa-Laa head lack lower jaw suits.
Revamp Tinky-Winky's functioning eye looks a normal one of that, unlike his pre-revamp and beta versions where their working eyes are small and thin. His jumpscare is more similar to Freddy's from FNAF 1 as the last thing you see in his jumpscare is his functioning eye. In addition, instead of holding himself on table, he appears in the bottom-left corner of the player's sight.
In Revamp Po's jumpscare, you can't see her eye sockets although, you can see a wire poking out.
In Revamp Laa-Laa's jumpscare, her eyes look somewhat like Noo-Noo's eyes from FNATL 3 and she looks as if she's throwing the player into the ceiling (possibly to brake their spine).
Revamp Dipsy in the Office has an animation, unlike his pre-revamp version.
Po as well as Plush Po are the only characters to change/distort their faces into unsettling smiles.
PTLD-93 somehow managed to change Po's face into creepy smile when he took over her. We can see this in the secret Po screen and the cutscene (because of the cheeks covering the eyes) from FNATL 2.
Although The Po 2.0 Head's eyes can turn back to normal, they are small, thin and grey, unlike Tinky-Winky's.
Instead of the 8-bit sprites, the tubbybots and Noo-Noo in FNATL 1 minigame appear as atari versions, similarly to FNATL 3.
Noo-Noo's the only character in the series to own a death screen for all 4 counterparts.
And that's pretty much it. Thanks for reading!
