From here, they will go to wherever Crowbar Jackson is, while they are still invisible.
His sheer girth would make his 'bully act' all the more convincing, and if anyone were to remark at his size: Well Up Yours Too: Being knowledgeable on things Pop gives 'Crowbar' a near-endless pool of insults and references, pissing kids off in a campy and over-the-top fashion.
Furthermore, due to the heartless kids already digging, the Chloes tactic of using them to speed up their digging is fruitless, as the kids will think they're trying to step onto their turf and either fight them or tell them to get lost.
So this means that they would have already gotten the treasure in those squares before he gets there, meaning without any interaction between them, the score is already 2-4 in the Chloes's favor.

The girls on the other hand focus almost entirely on digging, with Kay being the only one putting some attention on Jackson.
