They're all characters from Warner Bros. Loony Toons cartoons, which date from possibly the 1930s. I grew up with them so maybe have not noticed if there are any problematic names
I grew up watching a bunch of Looney Tunes and got the theme pretty quickly, but I'd never heard of Foxy. I was shocked how much of a Mickey Mouse ripoff it appeared to be (and as I'm now finding, close enough that Walt Disney himself stepped in to ask them to stop).
