Harvest Moon: A Wonderful Life Special Edition

Missable

You can dig up the tablets at the dig site (duh) from ~10AM to 5PM, provided Carter is inside. Talk to him to start digging. He won't be around on Van days though, so you won't be able to dig on the 3rd or 8th day of every month.

There's 5 tablets in total you have to dig up, one each for the first 5 chapters:

1. Tablet C (Chapter 1)
2. Tablet D (Chapter 2)
3. Tablet E (Chapter 3)
4. Tablet F (Chapter 4)
5. Tablet G (Chapter 5)

There's no tablet in Chapter 6, and the trophy unlocks as soon as you dig up Tablet G - before you even see you dug it up, actually.
