In a bowl, mix the cooked rice, grated carrot, beaten egg, breadcrumbs, salt, pepper, and garlic powder until well combined.
Shape the mixture into 12 small balls (about 1 inch wide).
Place them on a baking sheet lined with parchment paper.
Bake at 375°F (190°C) for 18–20 minutes, until golden and firm.
Let cool slightly, then gently press olive pieces onto each ball to make eyes and a spooky mouth. Top each with a green bean tip as a stem. Serve warm or at room temperature.
