From your comment I gather enough to conclude that the main premise of the accusation is “Shakespeare told by animals,” and I concur that that’s laughable.

It’s somehow baser than you suspect for the accusations against The Lion King – but more complex for Aladdin. I’d highly recommend Lindsay Ellis’ video for a history lesson exploring the nuances. I’ll at least spoil that Kimba has nothing to do with Shakespeare and that whatever level of tepid, token generosity you’re willing to grant the plagiarism accusations, it’s dumber than that.
