This is a , Girlilla.
She once was a girl then she turned into a gorilla. The only reason why she turned into a gorrila is because her parents wanted to make there sons life perfect, so they agreed to a curse. The curse is what it is told, if you and your beloved wife (they were talking to the father) were to ever have a female child. That child will turn into a gorrila at night. If not married by the age of 25 then she will forever be the gorrila.
The mother was quiet because she didnt want to mention that she was pregnant. In the family daughters can be rare, thats why she didnt think it was going to be a big deal.
two days later she decided to tell her family. "honey, what if its a girl, The curse?" is what the father said. "I'm sure its not real he didnt actually do anything he told us a couple words. Plus you know girls are rare in the family."
And thats how she became this gorrila, shes living happy though.
