Heart of Te Fiti using Oyumaru (aka. Plastic Clay)

I didn't think much of Moana when I first saw the movie. But it definitely grows on you when your 3-year-old asks you to watch it with her three times a day. The movie is actually quite the masterpiece and the music is absolutely beautiful! I can listen to the soundtrack all day long!

We are heading on a family vacation to Hawaii this year and BB keeps saying that she wants to go look for the Heart of Te Fiti in Hawaii. I wish I knew where to look...?

She has been obsessed with little gems, rhinestones, and marbles for a long time now. So when there was a movie that centred around a glowing green rock, I am not surprised that she would ask for one. This girl just loves her bling!

Sadly, it's not exactly the easiest thing to find available commercially. But hey, I'm always up for a good DIY!

I found this material at Daiso called OYU-PLA (aka. Plastic Clay) in their craft section while browsing around one afternoon. They put them together with their other clay products.

The description says that it can be reshaped as many times as needed. So I thought, 2 bucks, what's the harm in trying it out.

Follow along to see how I turn this little bag of "plastic clay" into the Heart of Te Fiti!

What You Need / Materials

Most of these items can be purchased through our affiliate links. Purchasing items through these links will not cost you any extra money. Please see our disclosure policy for more details.
  • Oyumaru (I got mine from Daiso)
  • Pot of hot water
  • Paper
  • Scissors

Put the Oyumaru into a pot of water and bring it to a boil.

This package came with 3 pieces of clay. I only used one piece for this project, but if you prefer your Heart of Te Fiti to be larger, you can use more than one piece of clay. The instructions says that the piece of plastic clay has to be heated in some water that is 80 degrees C (176F) for 3 minutes.

Take out the Oyumaru with a pair of tongs.

Careful, it's HOT! Dry it off with a piece of paper towel. You can tell from the photo that it's already become soft.

Shape your Oyumaru.

Roll it into a ball and then gently press flat to shape like the Heart of Te Fiti from the movie Moana.

Stamping your Oyumaru.

I made the spiral on the Heart of Te Fiti with a piece of rolled up paper. Keep in mind that all this has to be done before the Oyumaru returns back to room temperature. You'll notice soon enough that the plastic clay gets harder as it cools down.

If you are not done applying the details onto your Oyumaru, you can always put it back in the boiling water to soften it again.

As you can see, BB didn't even let me get a second photo in before she pried it away from my hand. She hasn't let go of it since. Literally.

Hanson's first comment was that it looked like a green cinnamon bun - LOL! If you don't have a 3-year-old at home disrupting your "crafternoon," I'm sure you can probably make one that's much nicer and more detailed than mine!

Did you make your own Heart of Te Fiti? I'd love to see it! Please share it with me on Instagram and/or use the #onceuponacheerio hashtag.
