Rinse the grapes, berries, and strawberries under cool water. Pat everything dry with paper towels so the tray does not turn watery. Dry fruit also looks shinier and holds decorations better.
Peel each clementine gently and keep the segments together so it looks like a tiny pumpkin. Remove the white pith if you can. Press a small celery piece into the top to make the stem.
Cut each banana in half crosswise, then stand the halves upright on a plate. Brush the cut edges with lemon juice to slow browning. Press two mini chocolate chips in for eyes and one for the mouth.
Take one black grape for the body and push 4 pretzel sticks into each side using the pointed end. Snap the sticks to different lengths so the legs look natural. Add a tiny chocolate chip dot as an eye if you like.
Peel the kiwis and cut them into rounds about half an inch thick. Hull the strawberries and leave them whole or halve them if they are big. These two fruits add the bold green and red that make the tray pop.
Stir the vanilla Greek yogurt and honey together in a small bowl until smooth. Taste it and add a little more honey if you want it sweeter. Set the bowl in the middle or at one edge of your platter.
Place the dip bowl first, then set the pumpkins and ghosts in separate clusters. Fill the open spaces with green grapes, kiwi rounds, and blackberries. Tuck the spiders near the edges so they look like they are crawling off the tray.
Cover the finished tray loosely and chill it for 20 to 30 minutes before the party. The cold fruit tastes crisp and refreshing. Bring it out right before guests arrive so the ghosts stay fresh
