Scary Shark: Who said everything made from FIMO has to be cute?

FIMO is a versatile polymer modelling clay, which, for some reason, is mostly used to create cute little characters and jewellery. But it doesn’t have to be.

As you can see below, you can also use it to make a ferocious shark with blood dripping from it’s teeth!

The polymer clay that I used was called Fimo, but other brands are available. All in all it’s a pretty cool material - once you’ve made your model you harden it in the oven, no need to wait for it to dry.

You can also use wire to create internal hidden supports, a technique that helped me create the shark. On the downside, it can be very hard to work with until it is properly warm - your hands can get quite sore trying to soften it up.

How to make one

What you’ll need

2 blocks of silver and 1 block of red, white, black, light blue and dark blue FIMO. You’ll also need some wire (1.5mm) and pliers and a pastry roller.

Step 1

First, create a simple wire frame to support the shark. Follow the measurements shown, it doesn’t have to be very accurate.


Before moulding the FIMO, warm it in your hands, it can be very hard to work with until it warms up. Also, to make a smooth join, repeatedly rub your finger over the crack - the friction helps.

Start moulding

Use the roller to flatten two silver blocks of FIMO into square sheets. Take one sheet and join the corners to form the shark ’nose’. Position the nose over the wire frame. Mould the FIMO around the wire to create the gums.

Take the other sheet of silver FIMO and join it onto the first sheet, as shown. Do this by firstly overlapping the FIMO and then cutting the excess away with a knife. Rub your finger over the join to smooth it out. Fold the FIMO over the wire and finish moulding the gums.

Flatten the light blue FIMO and create a rough circle shape. Place the sharks head on top. Push the blue FIMO upwards to create a wave like folds around the base of the shark.


Roll a white ball of FIMO and then flatten it. Now flatten a smaller black ball of FIMO and use a knife to cut-out a small ‘v’ shaped slice (the pupil). Attach it to the centre of the flattened white ball.

Mould some silver FIMO into the the shape shown (a curved arc with a triangular cross-section). Join it onto the sharks head and add the eyes, follow the illustration for exact position.

The gums and teeth

Make two tapered sausages of white FIMO by gently rolling them on a flat surface with your fingers. These are the gums, join them to the inside of the shark’s mouth, as before use the illustration as reference.

Make lots of pointy shark teeth from small pieces of white FIMO. Use a nail to make a series of holes along the gums. Push a tooth into each hole - bigger teeth in the centre and smaller teeth towards the corner of the mouth.

Blood and splashes

Add some blood and splashes to complete the shark. Both are made from thin worms of FIMO, but with a slightly bulbous end - just follow the illustration for guidance on how to position them.

For a gory finale, try making a half eaten little fishy and balance it on jaws teeth!

Do your own thing

If you haven’t used polymer clay, give it a go, it’s a lot of fun. But let your imagination wander, there’s still lots of unexplored territory when it comes to using this material.
