How do you cheer up your monster whe it doesn't eat food on Moshi Monsters?

There are a few requirements. First, boost your monsters' health by going to the gross-ery store to buy some food (buy some cheap ones to save rox!). Then, you have to boost up your monsters' happiness by tickling it( but when it gets annoyed, stop) or playing puzzles in the puzzle palace. Play your best because if you get a low mark on your puzzle, it MIGHT make your monsters' happiness lower. Now, after both your monsters' health and happiness is balanced, your monsters' mood should be good.(with some weird Words but you can sense that your monster is happy when it smiles)
