For each creature shape, take some marzipan into your hand and shape it according to the video instructions.
For the colored creature versions, add the food colorings to your liking to the marzipan and knead it in until the dough has entirely changed color. Adjust the colors to your liking.

Once you have shaped your woodworm, slug, maggots, and earthworm Halloween candy creatures, place them on baking paper. Brush diluted simple sugar syrup over the candy. That will lend them a realistic effect.

Let them dry.
For the presentation, I have spread cocoa powder over a plate with some dry active charcoal, and then I place the creatures over it. Enjoy it just like any other candy. You can use the pieces also for cake decoration!
