You are well named!
Seriously, having been a camp counselor for many years, the reason kids aren't supposed to have food in their own cabins is that it invites critters in. Racoons, etc. are very capable of getting into duffle bags or trunks, and they will destroy clothing and other necessities in their drive to find their way to a box of candy. Ants and other insects are also attracted to these things.
On the other hand, the food that's served to the kids is kept in the mess hall, which is nowhere near the kids' sleeping area. The mess hall is a "real building" with walls, doors, and locks. Animals can't get into it any more than they can get into your kitchen at home.
In closing, IF your camp allows you to send food, I suggest that you send only a small amount -- something that can be consumed that very day so that it doesn't need to be stored.
