When I bought my KSB, was told by the pet store (lol) that there was no way he could escape because they lack the strength to push up the lid. And that a branch is OK for decorative purposes, but it would absolutely never be used no matter what because there is no chance he will ever try to leave the ground. Well, about 2 years ago, I went on a trip for a couple days and after I came back, wanted to take the baby out. After about 10 minutes of searching through the substrate (since he's ALWAYS hiding down there somewhere), it became clear to me that he was not in his tank. I frantically searched my room and house for 3 hours with no luck. Finally, after all that, I found him hiding under a small bag of substrate that was literally right underneath the small table his tank was on. Apparently he climbed on the branch and pushed up the lid to get out, as at the time he was waaay too small to reach the top from the floor. Branch came out and heavy books went on top until some heavy duty clips were acquired. Lesson learned.
Side note, to this day at least once every week or 2 I walk in to find him fully extended up to the top of the enclosure, with his head by the screen. When he sees me looking he'll always just freeze, thinking that if he doesn't move maybe I won't notice him being bad. He's such a cute little noodle
