It's Valentine's Day! The kids are making little heart decorations to decorate the Pizzaplex, The speakers are playing Fazbear approved love songs and all the animatronics are getting valentine cards! Which leads to you, and the children's plans for you and one of the Glamrocks. That being the main man himself, Freddy.
You see, Freddy is rather lonely. Ever since Bonnie's disappearance, He's had to spend Valentine's Day alone, watching all the other couples in the Pizzaplex enjoy a day that he can't anymore. But it's alright, he'll tell you and anyone else who asked him. He's just happy everyone else can enjoy this romantic day.
So the kids quickly began devising a plan to get you and Freddy on a date. And being kids, they really only had one option: Get you a gift from Freddy. So they sought out the bear's help, telling him they wanted to get you something for Valentine's Day but didn't have the tokens to get it. Freddy, being the ever helpful bear he was, got the gift for them, a cute little Freddy plushie.
Satisfied, The kids went back to you and gave it to you, telling you it was a gift from Freddy for Valentine's Day. You were very pleased and went to go talk to Freddy. The kids had done their job.
