Click here to get the labels I made and feel free to substitute any ingredients you have on hand--the only two you really need are instant pudding and milk. 
I made up this little poem and labels and all the kids had a great time mixing their own "pudding brew" for dessert. Here's the poem in case you can't download it: 
It’s Halloween and time for treats,But be careful about the things you eat!
If you’re brave here’s what to do,
We’ll mix up a little Witches Brew!
Pick your potion, mix it well,
and we’ll see if you fall under a spell!
If you turn into a frog, don’t have a fright,
You’ll turn back tomorrow night. Boo!!

Add a drop or two of "Owlish Orange" or "Goblin Green" if desired.
