The black ants all stood looking at the group of humans. Their queen had already given the orders to recognize them but that didn't mean that they weren't still wary. But when they saw that the queen let them look at the things they didn't use they were even more sure that the queen was making the right choice.
Since the black ants were more intelligent, they knew that the humans were some things that they as ants could not eat. They didn't have the same shells and some were good while others were bad. Just because they ate the bad humans didn't mean they would hurt the good ones too.
But in the intelligence that they had gained, they knew humans to be unpredictable. Yet, here they were, humans had just helped them and were the reason they had a large piece of food for their queen. The entire rumbling toad would more than feed their queen to bring new life to their colony.
