Place the cauliflower into a small bowl, so that the hollow is facing upwards and most of the cauliflower is up out of the bowl. The bowl is just for stability. Fill with the avocado dip and arrange the pits as eyes. Decorate the white ”brain” by weaving thin strands of red and blue fruit leather between the florets to make veins and arteries. I wrap the bowl with cheesecloth and decorate with red food coloring to make it even more horrific!
