I kinda agree, Ducky. I thought they were a little weird, and that the 'wisdoms' and morals of the story were kind of blasted in the viewers' faces, but I just thought the yellowbellies were, well... different lol. They had some funny lines too, yeah.
I think it was because they did dumb things sometimes and were never... well... upset! Or angry. Did they ever get bored? Or sad? I can't remember at this point lol

Disgust is kind of a big word to say. And I'm not sure if the OP means it as disturbing in the natural sense or loathsome in a character quality sense or something. Anywaaays. I'm going to pick at the choices.
The stinky place wasn't really er disgusting to me. I kinda imagined it as spicy or salty lol cuz of Petrie sniffing the flower.
The spike as a pig was funny but a little unsettling for me at first xD.
I don't recall the animation of the seventh film to be bad. I think the characters moved their heads around more though.
Though not all the visuals were bad in Lone Dinosaur, I DO AGREE WITH YOU. Littlefoot looked QUITE weird there.
I can somewhat agree with the yellowbellies lol. But I wouldn't call it 'disgusting'.
The bawling on 11 was touching and funny, not disgusting xD.
For the last four films, by animation do you mean style and everything else as well? I know the later sequels had brighter colors or what not, but the animation was still great. Traditional animation I guess is more solid though.
The character bubbles on Friends for Dinner and Boring were just kinda funny not disgusting xD.
Tippy was. Annoying at times. I didn't even know Tippy was a boy until checking the wiki... which is kinda creepy since Tippy acted like some girl playmate the whole time (seemingly).
The character zoom out of Pterano was weird, yes.
Imaginary Friends was kinda childish, but I wouldn't call it revolting. While I know it didn't exactly add to the "plot", I don't see how people can't seem to understand it. Didn't you have stuffed animals next to your pillow as a kid

The Adventuring animation was great. Some of the creatures were a little creepy but not by much.
The creatures in Big Water were a little creepy when I watched it when I was young (er. lol). But the visuals were quite good actually, and stylistic too.
The tinysauruses weren't disgusting! They were funny and adorable lol. I guess liberals hate the little guys

Littlefoot's dream on 10 was kinda weird at first when I first saw it xD. But not disgusting. Quite surreal though.
