Love it couple things i would love to see!! If possible.
Multiple Monitor support allowing it to walk over multiple monitors.
Adding random randomly the word honk to text bars when it honks.
Perhaps open up internet windows too? Like a way that it can open up youtube videos would be very funny.
Picking up the goose would be nice to drag him to another location.
Uhm goose creating a puddle to swim in from time to time. Perhaps when it leaves it has the muddy feet again. So that the muddy feet dont only happen on the side of the monitor.
Perhaps some birdpoop somewhere.
Tho multiple monitor support, OR allowing me to pick which monitor it walks around in is probably what i would love the most. Cuss some games hide the goose which is sad xD
