Puzzle boxes

Us ponies just love the new puzzle boxes that the lady brought out here for us. I thought it was going to be hard to get the hay out of them, and we would all just be fighting and biting each other (okay, so actually biting other ponies is fun, it is only not fun when other ponies bite me) when she first brought hay out and put it in the boxes. But it turns out, the objective is to remove the net thing that is keeping us from grabbing mouthfuls of hay. See, the box is wooden and then it has this heavy net stretched on a metal frame that goes inside and lays on top of the hay. Last year, we would just grab that stupid net and drag it out of the box and stomp on it. So now there is an extra wooden frame that sits over top of the box. It is tied down to the top or has some kind of metal snaps on it. We discovered we can slide that frame over a little and by grabbing the net with our teeth and pulling it many many times, we can get part of it to stick up and then we can stick our heads under it and eat the hay. It makes a lot of noise banging around. We think it is so much fun, that even after the hay is gone, we pull out that nasty net thing until we can get it on the ground and stomp on it. Last night, the lady brought a different kind of net that she hung on the fence where it is solid boards. It is green on the back and has the net on the front. The hay goes on the inside. Ha! I am pretty sure we can tear that thing up in no time. The lady is definitely finding fun stuff for us to do!
