• Fimo Sahara Polymer Clay — used for the base or stem underneath the body.
• Fimo Chocolate Polymer Clay — for sculpting the feet.
• White Polymer Clay — for making the teeth and the whites of the eyes.
• Black Polymer Clay — for the pupils and eyebrows.
• Eye Pin — optional, for making your Goomba into a charm or trinket.

Tools

• Dotting Tool — helps create perfect circular indents and smooth surfaces.
• Chisel Tool — useful for making sharp line indents, like the mouth.

Step-by-Step Instructions

Each step is designed for beginners, with clear actions and helpful tips for best results.

1. Sculpting the Goomba's Body

1.1. Shaping the Main Body

• Start with Fimo Caramel clay. Break off enough clay for a small figurine.
• Roll the clay into a smooth, even ball between your palms to remove any creases or cracks.
• Begin to form the basic triangle shape by pressing your fingers around the ball, pinching the bottom corners slightly and gently squishing the ball’s top to create a chubby, tapered shape.
• The result should be a fat, squat triangle—wider at the base and slightly rounded at the top, like Goomba’s iconic mushroom cap.
  Save
• Gently flatten the triangle just a little to create a slightly stable base, but don’t flatten it too much; you want the Goomba to look plump and three-dimensional.

2. Adding the Stem/Base

2.1. Creating the Cylinder

• Take a small amount of Fimo Sahara polymer clay.
• Roll it into a ball and then roll it back and forth on your work surface to turn it into a small, rounded cylinder or tube. This will be Goomba’s stem.

2.2. Preparing and Attaching the Base

• Using a cutting tool or blade, slice off just the very tip of the cylinder so that the end is flat.
• Gently press and blend the flat tip into the bottom of the triangle body shape, creating a seamless join where the “stem” meets the body.
  Save
• Smooth out any rough edges so the stem looks like a natural extension of the body.

3. Preparing for Assembly

3.1. Inserting the Eye Pin (Optional)

• If you want to hang your Goomba on a keychain or necklace, insert an eye pin into the center of the Goomba’s head.
• Push it down securely but not so far that it comes out of the bottom.

4. Sculpting the Goomba’s Face

4.1. Creating the Mouth

• Use a chisel tool or the thin end of a dotting tool to press a line indent across the lower front of the triangle body.
• Make sure the mouth is centered, and extend it wide enough to give Goomba a suitably angry expression.

4.2. Making Indents for the Eyes

• Take a large dotting tool or any small rounded object.
• Press two indents above the mouth, evenly spaced, for the eyes.
• Make sure the eyes are symmetrical and aligned horizontally.

---

5. Adding Goomba’s Teeth

5.1. Creating and Placing the Teeth

• Break off a small piece of white polymer clay.
• Roll it flat using your fingers or a smooth, round object like a pen barrel.
• Cut out two small triangles from the flattened clay—these will be the pointed teeth.
• Place one triangle onto each end of the mouth indent, press lightly so they adhere to the face. The pointed ends should face downward, resembling fangs.
• Make sure the teeth are secure but do not squish them completely flat.

---

6. Making the Eyes

6.1. Forming the Whites of the Eyes

• Roll two tiny balls of white clay.
• Place the balls into each eye indent, gently pressing them down and flattening them with a dotting tool so they fill the indents and become round, even eyes.

6.2. Adding the Pupils

• Take a very small amount of black clay and roll it into two tiny balls.
• Place one black ball onto the inner side of each white eye. The pupils should slightly face each other, making Goomba’s stare look intense and focused.
• Press each gently to stick them in place without distorting the eye shape.

---

7. Attaching the Feet

7.1. Shaping and Attaching Goomba’s Feet

• Break off two small pieces of Fimo chocolate clay and roll each into a small ball.
• Shape each ball into an oval by gently rolling between your fingers.
• Slightly flatten the ovals so they become stout, blob-like feet.
• Attach each foot to the base of the triangle body, spacing them apart for balance.
• Press lightly to secure, ensuring the Goomba will stand upright.

8. Adding the Eyebrows

8.1. Sculpting Angry Eyebrows

• Take a small bit of black clay and roll it into a skinny, tapered cone shape.
• For each eyebrow, position the thicker end close to the inner corner of an eye.
• Arch the eyebrow so the thin end curves up and over, like a stretched “n” or a frown.
• Repeat for the other eyebrow.
• The eyebrows should have dramatic, angry curves that give character and emotion to your Goomba.
• Adjust as needed to make them symmetrical and expressive.

---

9. Baking and Finishing Touches

9.1. Baking the Goomba

• Carefully transfer your assembled Goomba to a baking tray lined with parchment or foil.
• Bake according to your polymer clay’s instructions (usually around 110–130°C or 230–266°F for Fimo, but always check your packaging). Baking time depends on the clay’s thickness, usually between 15–30 minutes.
• Let your Goomba cool completely before handling further.

9.2. Glazing the Figurine

• If you want your Goomba shiny and durable, apply a thin layer of glaze using a small paintbrush.
• Let the glaze dry thoroughly as per the manufacturer’s instructions.
