After Freddy Fazbear's Pizzeria shutdown, Sae Tan left Fazbear Entertainment, became rich, moved five states away, made his own company called Tan Corp, and built his own kid-friendly place, the Animatronic Kingdom, named after the group of animatronics he helped design and create. He even bought them back from Fazbear Entertainment to be reused at this new location. At this time, his other cousin Frankie was also developing his own place, Frankie's Funhouse. He even later develops a time machine.
Mr. Tan now wears a nice tan suit, with a fancy red tie.
Mr. Tan is known for his generous donations to charity, and his cheerfulness to help others. This is why he became rich on hippie donations to him.
