Harvest Moon: A Wonderful Life Special Edition

Can be obtained starting Chapter 2.

Before you can hybridize crops, you not only need to reach Ch. 2, but also meet Tartan, a two headed, talking plant that lives inside Takakuras house. Tartan won't live there from the beginning though, he'll "move in" once Takakura comes back from a trip to down one day because you ordere something (Bird Feed, for example). After you ordered something from the ledger, simply enter Takakuras house when he's in there - around 7PM should work to trigger a cut-scene where you meet Tartan.

If you have trouble getting the cut-scene, re-enter Takakura's house repeatedly. Rumor has it that the chance of you unlocking Tartan is increased depending on how hard you worked on your farm, but I unlocked him straight away and I didn't have an excessive amount of crops. It's still worth a shot if you can't unlock him though.

Once you've met Tartan, you'll have to become his friend. Luckily, he requires no presents to become your friend - you simply have to talk to him a lot. If you want, you can just keep talking to him until the Hybridize option becomes available, or stretch it out over a couple days. Regardless of your choice, once it becomes available you can combine two crops or seeds into a new one, provided you pick the correct ones. Even then, it's not a 100% guarantee that you will obtain a hybrid crop or tree though, so you might want to save your game before you start hybridizing.

For the trophy to unlock, you have to hybridize two hybrid crops/seeds to obtain a third generation seed. If you want, you can experiment with hybridization, or simply use my recipe:

1. Hybridize a Strawberry and a Turnip to get a Dhibe Seed.
2. Hybridize a Strawberry and Melon (NOT watermelon) to get a Berrylon Seed.
3. Hybridize your Berrylon and Dhibe Seeds to make a new, bell-looking plant that you can name yourself and unlock your trophy.

Make sure you put in the crops/seeds in the order above, or you may get different results!

Remember, you can buy seeds from anyone on Vesta's Farm, and you don't need to plant them first to use them in hybridization.
