Different food items will be falling from the sky and your task is to "Mouse Click" and drag the food to the proper animal plate in the allocated time period. You have three lives per level so be quick and do what ever you have to do to feed the Goat, Monkey, and Dog.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
