I made this today as a surprise for my niece.I looked around at a lot of recipes but i didn't have all the ingredients in most of them so i ended up just making my own.

Swamp Punch



First mix
1 can of mountain dew
1 teaspoon lemon juice
1 cup of ice
In a blender until smooth while that is blending i used green cake gel (or red if you want fake blood) and went around some of the edges and smeared it with a knife to make it look like slime. pour the mountain dew mixture into the cup and add gummy worms, Fake eyes (i made mine from a gumball and brown cake gel).Then i put whip cream on the top and drew a web with brown cake gel and added a plastic spider on top.
