you're a manager for a Freddy Fazbear's pizzeria.
you're finally free from work. You proceeded to go to a nearby convenient store for something to eat. After your meal you notice a gumball machine outside the store.
"gumball machine, have a chance to win a free gumball swivelhands! (sponsored by stans budget tech)"
you might as well just buy one. Both as a little treat and a chance. These gumball are served in capsules somehow... And...
"congratulations! You won gumball swivelhands! Enjoy your winner gum and your new gumball machine! Go to any stans budget tech and claim your prize!" you found this ticket besides the gumball in the capsule. Lucky you.
next day. You went there and picked up the model... Apparently its one of those vendor animatronic just like in your diner. It can also chew gum. You placed it in a box. And drove your way to your Fazbear's pizzeria before opening hour. You placed her down at a spot, filled her head with gumball... And started her up.
"sup" she just blows a bubblegum.
