What unique item is included in the Green Ghost Glow cocktail's serving glass?

The Green Ghost Glow cocktail is distinctive due to the inclusion of a flashing ice cube in its serving glass. This unique feature enhances the visual appeal of the drink, making it more fun and engaging, especially in a vibrant social setting like Dave and Buster's. The flashing ice cube not only adds a playful element but also serves as an eye-catching focal point, drawing attention to the cocktail and creating a memorable experience for guests. The other options, while they might be common garnishes or additions to cocktails, do not provide the same kind of interactive and visually stimulating aspect that the flashing ice cube delivers. This highlights the creative approach to cocktail presentation that sets the Green Ghost Glow apart from other drinks on the menu.
