Major film studios' respective cartoon mascots

Here are what I think should be the major cartoon mascots of a major film studio:

Universal Pictures' mascots are Rocky and Bullwinkle, Paramount Pictures' mascots are Ren and Stimpy, Warner Bros' mascot is Bugs Bunny, and Disney's mascot is Mickey Mouse

I was gonna make Popeye or Betty Boop Paramount Pictures' mascots, but the rights to those characters go to King Features Syndicate. I also was gonna make Woody Woodpecker the mascot of Universal Pictures, but he isn't as remembered as Bugs Bunny or Mickey Mouse.

NOTE: I own nothing.
