Going t'other way, Pepper Pig got criticised* in Australia for an episode with a friendly spider....
One of the things that you don't see in Modern Britain are the Tom and Jerry cartoons. Admittedly the violence (frying pans to the head, etc), racist themes and so on would be difficult to get past the schedulers, even with "trigger" warnings. But Bugs Bunny, Wyle E Coyote and Roadrunner and other former staples are conspicuous by their absence too.
There have been toned down "lite" versions produced in recent years, but the animation styles and stories are cr@p.
It'd be nice to see the originals as late night specials on BBC Four...
* The episode was probably dropped...
