To successfully obtain the toy boat in Untitled Goose Game, follow this step-by-step guide:

1. Locate the Toy Boat: Start by heading to the Pub area. The toy boat can be found in the sink situated at the back of the pub.

2. Activate the Water Tap: Once you are near the sink, turn on the water tap. This will initiate the flow of water into the sink.

3. Fill the Sink: Allow the sink to fill with water. You will need to keep the tap running until the water level rises sufficiently to float the toy boat and make it accessible for you to grab.

4. Distract the Pub Woman: The Pub Woman will notice the running tap and will attempt to turn it off. To effectively distract her, create mayhem around the pub. You can honk, steal items, or cause disruptions that will lead her to chase you, which will keep her away from the sink.

5. Grab the Toy Boat: Once the sink overflows, the water level will rise enough for you to reach the toy boat. Quickly grab it to complete your objective.

6. Make Your Escape: After obtaining the toy boat, make a swift exit before the Pub Woman can stop you. Stay alert and avoid her as you leave.

Remember, timing and distraction are key elements in this task. Patience will also be crucial as you wait for the sink to overflow, so strategize your movements wisely to ensure the success of your mission!
