I cannot make 2 Honey Makers get close enough to each other in Map 21 for this to happen, unless I by some happenstance, get stuck on the rope without falling off it, but that's a bug that's only ever happened for me once. Using the Mari-o skin to get the box that's higher by the ropes, it's still too far for the upper Honey Maker and it stops chasing and returns to it's passive location.
