Disney Copyrights?

My daughter and I watch Anime together sometimes.
Cartoon Network has started re-running one of our favorites Dragonball Z.

In this particular series there is an evil wizard named Bobbidi who is the son of an even greater (but dead) wizard named Bibbidi who created the ultimate engine of destruction name Buu.

Bibbidi, Bobbidi , Buu, I can't believe the lawyers at the house of mouse have not jumped all over this one yet. Granted Cinderella was made a long time ago but they always seem to figure out a way to extend their trademarks.
