Why is this the answer?

The answer is cherry because this fun riddle uses clever word pictures to describe a small, sweet fruit we all know and love. We can break down the riddle into three amazing clues that match the parts of a cherry perfectly. First, let us look at the clue: "I wear a red robe." A robe is a long piece of clothing, like a fancy gown or coat. Think about the color of a cherry that is ripe and ready to be picked. Most cherries have a beautiful, deep red skin that wraps all around the fruit. This shiny, smooth skin is exactly what the riddle calls its "red robe." It is the cherry's special, colorful outer covering. Next, the riddle talks about a "staff in hand." This is a playful way to describe the cherry's stem. When a cherry is still growing on the tree, it hangs from a small, straight stick that grows from the branch. This stick is the stem. When you pick a cherry, you often hold onto the stem, and it looks a little like a walking staff or cane. The cherry is the main part, and the stem is held in its "hand." Finally, the riddle gives the clue about a "stone in my throat." This is the best clue of all. When you eat a cherry, you will find a hard seed right inside the center of the sweet fruit. This hard seed is often called a pit or a stone. It sits right in the middle, or the "throat," of the fruit. You eat the delicious, juicy part all around it, but you definitely do not eat the hard stone. The cherry keeps its stone safely hidden until it is ready for someone to plant a new tree. These three fun clues put together perfectly describe the wonderful cherry.
