Haha... yes, 'spirited' is a good way to put it. Ours are strictly indoors and otherwise only venture to our screened back porch. It's very sad when animals are hurt like that and I can't put myself through it, so only inside house pets for us.
Its our first time with Bengals and love them, but it's like having two year olds that can jump 5-6' up. If you have to ask yourself, "would or could they...??" the answer is automatically YES!! They'll get into anything and everything, so it's like child proofing your entire house only extending that concept to any reachable height. You can watch them evaluate and think through something and still surprise us, but that's the fun. One of them learned to turn on/off my Xbox with her nose and it was hours of entertainment for her. Constant things like that. You just have to be careful and Bengalproof things you want safe and especially to prevent them from potentially getting hurt in the process.
