No, you know baba is you, where you can stack a rock on a skull, move both around, and separate them later.
... which you can do. turn one of the blocks into a target, the other into a pushable block, then turn the target into a pushable block again.
voila! two pushable blocks stacked on each other
(the [2] is stacked on the [1])
But you don't DO anything with it. You could push it to the left... if you wanted... eh... hooray
well this was made in 36 hours ok
