Since Wukong (reluctantly) let you live on flower fruit mountain with him, in a seprate cabin of course, you would take walks at night instead of sleeping. You nearly slept, it gave you time to think and that wasn't good. Anyway on this particular night you found a baby monkey, which it wasn't unusual for there to be any monkey but this one was all alone and crying and maybe hurt, since you had no idea how to take care of one you went and woke up Wukong, he was not happy when you woke him up but decided to help seeing it was hurt. While he went to go get some bandages you were watching it, while you moved your gaze from it for one second it was suddenly falling off the bed you put him on.
