(It's been a while since Dora has been seen in Steve's company, so this time they are together and, it seems, for good reason.)

This time, Steve needed to walk to the nearest village to bargain with the locals. And since Dora was staying at his house at that time, he decided to take her with him to show the neighborhood.
The road to the village was calm, so nothing foreshadowed trouble. However, when the couple approached the fence, they noticed Iron Golem, who was standing guard over the village. Realizing that they were unlikely to be able to prove Dora's inoffensiveness to this guardian, Steve decided to convince him that she was not a scary and evil mob, but an ordinary cute animal similar to a fox.
It seems Steve's explanations only confused Iron Golem. (It is unlikely that these two will guess that Iron Golem initially did not see Dora as a target for attack, since he does not recognize Creepers as a threat.)
