How can I entertain my female lop?

My rabbit coco gets bored real easily. She pulls at her water bottle and she dumps out the water in her water bowl and moves it at opposite corner of her hutch. I asked my friend and she says that the rabbit could be throwing a tantrum. Coco doesn't chew on here water bowl btw, anyway my friend says my rabbit could be bored. So what can I do that will entertain my rabbit? without spending money?
