A monster that's at 100% happy earns coins twice as fast as a monster that's 0% happy - that is, if you look at the monster's info, the green "rate" figure goes up (though the Max figure stays the same). This information is scattered around on individual monster pages, but possibly could be worth summarising on one article somewhere...
