You can get a 3p (2 honey makers and player) in level 21. For goblin's you have to find a secret place in level 19.

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.
