Get into the garden

get into the garden is the first listed Mission on the To-do List, the mission involves getting into The Garden.

How to complete
If the Untitled Goose grabs the Radio that can be found on top two sacks of (presumably) dirt, the Groundskeeper will notice and open the door to The Garden, then the Untitled Goose can enter.

It's also completable if the Untitled Goose turns on the sprinkler because if the goose does so, the Groundskeeper will go out and turn it off, this will make it possible for the Untitled Goose to enter The Garden.
