In a bowl, combine cream cheese, herb cheese, and grated cheese. Add granulated garlic and stir with a spatula.
On plastic wrap, spoon mixture into a triangle shape (about 7-8" long and 5" wide). Wrap and refrigerate for 3 hours. Transfer the triangle shapped shark to a serving board.
Sprinkle the top edges about 1" around with poppy seeds to create the “back.”
The center should remain white to form the “belly.”
Place chorizo slices on the bottom to form the “mouth.”
Place cheese triangles (yellow triangles, 1" for the teeth) on top. Make eyes from .75 cheese circles and place 1/5 olive slices on top.
Arrange blackberries around the shark. Add green long candies (seaweed) around the edges. Place starfish or sealfe gummie candies in the corners. Arrange cold cuts, crackers, and pretzels.
Garnish with fresh sage leaves and serve.
