"Miss Piggy is the ultimate diva, a prima donna of the highest order, and one heckuva healthy eater, too. As an actress, a singer and a force of nature there is no one else anywhere who is even remotely like her. She steals the show, and if you get between her and the spotlight, watch out. Her karate chop is not to be messed with. Hiii-yaaaa!!!"
Every Muppet has different things that they like. For every unique object that they like that's placed on the stage, the Muppets's happiness will increase by one (in other words, placing two of the same liked item will still only increase happiness by one ).
