These two Hmong couple didn't have any kids, and really wanted a kid since they were getting old. So everyday that they went to the garden they would call out loud on how much they wanted a kid. A poj txoj overheard them and turned itself into a baby boy. The two couple found the baby and thought it was a gift from god. They brought the baby home and took care of it the best they could.
Years have passed and the baby boy was getting bigger. The mother also notice that the father was getting very weak and sick. He would always complained that his neck hurts but couldn't find anything wrong. She went to a nearby neighbor who was a shaman and asked him to look into why her husband was getting sicker by the day. After looking into his things (I don't know what you call it) he asked her if they had found a baby a couple years back. She answered yes. He then asked her that every night that they slept does the baby always faces the father. She thought for a bit and answered yes. He then told her to go back home and tell the father that she was going to the garden but then go and wait til night fall and peek through the walls of where the husband sleeps at and she will then find her answer to why her husband is so sick.
She then went home, gather her garden stuff and told her husband and baby that she was going to the garden and may not return til nightfall. She went on her way but stayed nearby. As night approached, she slowly and quietly peaked through the wall of where her husband slept. What she saw horrified her to death. The baby boy had turned into a poj txoj and was sucking her husbands blood from the hole it had made on the husband's neck. She was too scared to go back home the whole night.
As morning came, she finally got the courage to go home. As she went inside the boy woke up and said, "Why'd you go so long mom". She froze and studdered that since it was too late she decided to just sleep there and wait til morning to come home. She was so shaken the whole day that she decided to go see the shaman. The shaman told her to build a cage and dig a hole enough for the cage and try to trick the poj txoj into the cage and burn it. So she went back home and told her husband about the boy and what she saw. She also told him about the plan but little did they know the poj txoj already know what they were planning. So it went along with the plan and followed them. As they approached the hole of where the cage was, the poj txoj pushed the dad into the cage, laughed and said, "Since you two know what I am and were mean enough to kill me I'm going to kill you first." It burned the dad and the mother could do nothing but watched her husband die. She was so scared and angry at the same time that when the poj txoj wasn't paying attention she ran off.
The poj txoj started chasing the mom. The mom ran towards the mountain to get to the other village where her relatives live. As the poj txoj chased after the mom it kind of lost her. It came upon these travelers and asked them if they'd seen its mom. The travelers said they haven't seen anyone besides the lady who went toward the mountain and pointed to where the mom was at. The poj txoj looked and said, "that's not my mom. My mom is pretty. That lady has horns." No matter how much the poj txoj looked at where the mom was at it kept saying that it wasn't its mom. The thing was that, the mother was carrying one of those hmong chairs you see shaman use during rituals on her back, with the legs facing outward (if you can picture it). So that made the poj txoj confused that the legs were horns since it was sticking out towards the moms head.
So the poj txoj decided to chase on down the road and never saw its mom again.
