When he was a little over a year old, DS4 reached up inside the wall of a 4-year-long child-proofed room through a tiny hole in the fireplace (which has a cast-iron stove in it) and pulled fiberglass insulation out of the wall. We only figured out what had happened when we saw the insulation in his hand, and asked him where he had gotten it. We never would have figured it out otherwise!
About that same age, he also locked me out of our master suite. By the time I got the door unlocked, he had his arm wet to the shoulder from the toilet, he had a penny in his hand, and he was reaching for the outlet. I wouldn't have believed it if I hadn't seen it! It's too much to be believed! I always joke that if we'd only stored drain cleaner in there, he could have dug that out and had it ready to be swallowed, allowing him to hit the jackpot of ways a child can hurt himself!
Now, he never really tore up the house or our property, but he was always finding astonishingly creative ways to scare the fool out of me! He knew no fear--still doesn't!--and he liked to explore.
Not exactly the same, but similar, I think?
BTW, his older brother is HG+. We don't really know with DS4 yet. He might be GT or he might not.
Dunno if that helps at all...
