It's a cartoon. Notice that characters also get blown up, turned into fried chicken, wearing different outfits, etc., and are back to normal in the next scene...
Budddy,it's supposed to be "cartoonish", ya know? Like when daffy duck gets a shotgun shot at him and he has all of those holes, he never has them for more than a minute. Go looney toons!
Glenbardnationkleanosopo, I don't know where you're from but where I come from A-Ok (a hyphenated word) is a real saying. It's not 'a ok' or, as you say 'an o.k.' A-OK is perfectly correct!
