Rune Factory: A Fantasy Harvest Moon Tips

Egg Show [Spring 23]
Collect an Egg from a captured Kokehoho and bring it to Godwin in the Plaza. If you win you'll receive 50,000 G. Second place is 30,000 G, and last place is only 5000 G.

If you're crafty, you can buy a Small Egg from Neumann's farm and enter it into the contest. Make sure you do this several days before Spring 23, as for some reason the game makes it rain right before the Egg Contest date. If it's raining then Neumann won't be in his shop.

You'll have better chances at winning if you bring a L. Egg.
