Marshmallow Bow And Arrow

We do secret Santa at school (8th grade) and I get my friend marshmallow theme things. I made a gun, marshmallow and bow and arrow marshmallow, marshmallows and mini. What else? I do not want to spend too much money. Suggest something less than $ 20 please

How about a cup and a cheap box of instant cocoa with mini marshmallows? Hope that helps ...
