Hey there
I’ve just watched the episodes “Mechanical Plague” and “Trapped” and I realized that the Thundercats look kind of different.
They look more a lot more cornered and akward.
Their animations are more stiff and everything looks “older”.
Anyone else noticed that?
Did the animation technique change in these two and the following episodes?
Thanks for your help!
There were several badly animated episodes like the ones you mentioned throughout the series
I think this happens when they either rush an episode or get cheap animators
It’s like that with most cartoons and anime
I’ve always thought the episode 'The Mountain" looked like it hand a yellowish tint to the entire episode.
Thanks for the answers! I was just curious if I make things up! 
But it’s definitely a different style of animations in these two episodes!
I didn’t notice this as a kid but it’s everywhere! Several random episodes with bad animation in virtually every old cartoon and anime!
