To clarify what the Handiness upgrade for Happy from the fridge is, it's Fresh Maker and gives the How Fresh Moodlet (4h +1). Only the chef gets this moodlet, not those who eat the meal.
I am working on the Emotions guide, and think that since this list will definitely expand it will be the best place to link people who want every possible means of producing emotions. I am going to list the common means on the guide so that people can get their Sims in the 'Very' moods no matter what their traits are, then let visitors know that they can find even more potential moodlets here. I love the specificity of some of these, but they're not right for the strategy guide. I also don't want to feel I'm always behind on the latest info, as there will be many more when we get expansions and the Sims Store comes along. I will definitely update it, since Emotions are going to be a part of the game here on out, but this will stay the master list.
