Start by preparing your cups. With a black marker pen, draw a jack o’ lantern face on each cup. Check the length of the straws against the cup and cut them down a little if needed.
Measure out the orange juice and pour into a blender.
Add the smoothie mix and blend until smooth.
Spoon or pour into the prepared glasses.
Top with a straw, placed in the middle of the cup like a stalk. Serve immediately.
Notes
To decorate: Clear plastic cups or glasses black marker pen (I used a sharpie) and green straws.
