In Animal Crossing: New Horizons, you should stumble upon a seagull named Gulliver.
You will find him washed up ashore at the beach nearby. He should appear on the second day onward.
Here’s how you can help Gulliver find communicator parts in Animal Crossing: New Horizons (ACNH).
Talk to Gulliver
To help Gulliver, talk to him. He will be lying on the beach.
Speak to him a second time to get him awake. He will then ask for your help to find five communicator parts.
How to find communicator parts
You will need to find five communicator parts all over the beach surrounding your island.
The key is to look for those tiny spots where you see some water squirting out of the sand.
Use your shovel to dig out the communicator parts.
To get a shovel, craft it using the work bench.
Once you have all five of them, speak to Gulliver again.
You will get a mail from him within a few days, and also get some Miles for unlocking an achievement.
