you were exiting bob-omb battlefield (which is now peaceful ever sinse Mario came) when you noticed something different, there was a shy-gal here with the other bombs, you decided to come back just to see better and you noticed that she also had a fuse like the other bob-ombs, she then noticed, turned around and looked at you "Oh hey there! Haven't seen you around here, came here to see these cute little bombs?" as she lifts a bob-omb to be at head-height
