Preschool Snack Ideas Needed

At our preschool the kids take turns bringing in a snack for the class. I am very excited because I get we get to bring treats on Oct 25. I love doing themed treats, so I love that our snack date is so close to Halloween.
Last year I bought these cute snack boxes on clearance after Halloween. They are pretty much small popcorn boxes. I would love to come up with a snack to put in the boxes. That’s where I need some help! I’m not sure what to put inside.

Last year for preschool snack I made these monster pretzel rods.

I could really use some help with inspiration. There are a few guidelines I have to follow:

No cupcakes allowed. – Cupcakes are for birthday’s only
No nuts – my daughter is allergic
It is a snack time, so something with an element of “real food” would be nice. I try to avoid pure sugar.

Here are some things I have seen on Pinterest that I think are cute.

Thanks for your help!!!
