Thank you for the puzzle! I like the theme. One note is that using "wobble" as a hint for "careen" in 8D doesn't feel quite accurate - to me, careening is moving really fast and out of control, while wobbling is moving quite slowly but out of control as a result of being off balance. You might say that after an object wobbles and falls, it begins to careen
I think careen has multiple definitions, one as “go at top speed” and another as “sway from side to side,” the latter of which I was invoking. But I appreciate your feedback and thanks for solving!
