Use sturdy wooden toothpicks or small appetizer skewers about 4 to 6 inches long (10 to 15 cm).
Start with the grape - Thread a green grape onto the bottom of each toothpick. Leave a little room at the end of the toothpick so there is a place to hold it.
Add the banana slice - Hold a banana slice flat in your hand and carefully push the toothpick straight through the center. This keeps the banana from tearing and helps it sit flat on the grape.
Add the strawberry hat - Thread a strawberry onto the skewer through the wider end first, so the pointed tip stays on top and looks like a Santa hat. Gently press it down so it touches the banana slice, but do not crush the fruit.
Top with the marshmallow pom pom - Finish each kabob with a mini marshmallow on the very tip of the toothpick. Push it straight down, twisting slightly if needed so it does not split.
Repeat with the remaining ingredients until you have 12 Grinch fruit kabobs.
