Some like to "dig" in various things - blankets, towels, their litter box, the carpet, etc. If you've got a digger, maybe give him something he can dig in all he wants, like a cardboard box with shredded paper or something.
Most bunnies like to chew as a form of play, also. This is actually essential, as their teeth keep growing throughout their lives, so they need to chew on wood or something to grind them down as they get older. My little guy, Flash, likes to chew on cardboard, old phone books, and the 2x4 pieces of wood that I put along the edges of my couch to keep him from getting under it.
They also sometimes like to run around, or jump up on things. Flash has figured out not only how to jump on to the seat of my couch, but also on to the back part. He thinks he's part cat! Luckily, he hasn't figured out that he could jump up on chairs and using those to get on to tables.
They all have different personalities. You'll just have to watch and see what they like to do, then give them a way to do it without being destructive. If they like to dig, give them something to dig in. If they like to chew, give them chew toys. Don't expect that you can stop them from being destructive without giving them a better alternative.
