If I left a pop-tart uncovered in my locker on Friday, will it rot?

Okay so Friday morning I went to my locker after buying breakfast with my friend at school. She bought us pop tarts.The bell rang and she had to go to she set her pop-tart in my locker. Then when I garbed my books it fell on the floor and i put it back in because I was going to throw it away later. I completely forgot on Friday and now its Monday. Will it like attract flies, or turn into maggots or something? I just want to throw it away and I don't want any bugs in my locker! Please help.
