HELP Gulliver is on my sisters island! (spoilers)

[sleepydreepy]

Gulliver is on my sister's island, but she is having some problems fulfilling his requests!

Does anyone know how to find Gulliver's communicator parts?

Are they just buried randomly in the sand, or is there a method?

Dig them up in the sand. There's little water sprays coming from the spots. Can be the parts or clams, I already completed his request.

Ok, I'll tell her! Thank you so much!

Potential Spoiler:
When you find all the parts, he says something along the lines of, "When you receive your prize in the mail, make sure you're wearing fins."

Could it be? Is this how we unlock diving?

I don't know how to do the spoiler tag. Sorry! Highlight the text to see what it says.
