In this game, you are a dog:

You must save 4 ducks...:

...from hungry foxes...:

...by pushing them into escape portals:

You must save at least 3 of the 4 ducks to advance to the next level. While the ducks are in play, you can chase the foxes away. However, once all the ducks are gone, the foxes will turn on you. You must then escape through a portal yourself.

For bonus points, pick up the bones:
