The Login Screen is where you type your username and password to login to the Moshi Monsters site. You can get Moshi Monsters MoPod codes by getting the Moshi Monsters Magazine, buying Moshi items at stores, winning contests or sometimes, The Daily Growl will give you a free code from a puzzle or riddle. You can enter codes by pressing the 'Got a Secret Code?' button at the bottom-lefthand corner of the screen. You have to be logged in to do this. There is now a box that will keep you logged in for two weeks maximum if you click it.
Before Moshi Monsters was redesigned in 2013, Secret Codes could be entered on the login screen.
