REALLY unhappy wekinz!

[cleothepig]

Playing games like others have suggested. I also think that answering quizzy's questions increases your happiness. You can earn tons of kinzcash that way too! Best of luck increasing your happiness! :]

Try feeding your pet lots of food, playing games and give it tons of baths.

One other solution that no one listed here is to go to Quizzy's and answer questions for 10 minutes or so. Each answer gives you 1 point of happiness and you get to 100 really fast.
