If that was all, I would be fine with him if he was just an annoying comic relief. It was more of his belligerent and rather loud “NO!” when Littlefoot just asked for help in getting his father (considering it turned out to be Wild Arms’s fault in the first place that Bron was in trouble!)
As for Grandpa Longnenck’s new voice, I guess it’s ok, though it makes him sound younger. Mr. Threehorn’s is ok. I get that they can’t help it that the voice actors died.
As for Wild Arms, I was thinking that maybe Chomper could forget that he was a bug eater, just this once. :lol_ducky
