It's still in top 4. And I'm guessing either it was simply because Foster's Home and Billy & Mandy were getting better ratings, KND was winding down around this time, more shows this year meant less airtime by default, or maybe they didn't really have anyone on the show they could plaster on the Yes bumpers like Foster's Home with Cheese, Billy & Mandy with Fred Fredburger, and Ed Edd n Eddy with Ed.Why did KND take such a sizable drop between 2005 and 2006?
