Bubbles and minefields do not play well together.
In fact, I think you could craft a variation on the Chicken, Fox, and Grain puzzle with these two things, plus a kitten.
You have a bubble, a kitten, and a minefield. You need to transport all three of them across the river…
Wait, that doesn’t work, because you can’t trust ANY of these things alone together. Maybe add a bag of kibble for the minefield to play with.
