My bunnies LOVE to chew on everything EXCEPT the toys I give them, so I know what you mean. I have had a lot of luck with cardboard boxes. I usually cut a small tunnel in one side so the bunnies can get in and out, and they spend a lot of time hanging out in the box, as well as spend a lot of time “remodeling” the doorway.
As far as flinging a food dish, I don’t use a large food dish because I only feed one Tablespoon of pellets in the morning, and one at night, so I usually just put it somewhere on the ground, and my bunnies eat it within an hour or two, so there is nothing to dump over.
I agree with Beka on the water bottle, there should be a way to hang it outside the cage, so that just the metal tip is inside the cage. I actually use water crocks for my bunnies that screw onto the side of the cage. They are made out of a very hard plastic that the bunnies can’t chew. I got these from the cat or dog aisle at Petsmart.
