For this video we have compiled all theories about Secret Bosses from the Deltatrune chapter 2 survey. We'll talk about Woody Theory, Apple Girlington, Soul mode theories, and shadow crystals. There's plenty to cover!

On this Deltarune Theory Survey from August 2024 to June 2025, over 2000 people rated what they thought about old theories. The largest sample size for the fandom. We have ratings, text responses, and old theories to look back on. Which theories were liked and why were they made? More videos where we'll talk about other categories from within this survey will come. See you for those too!
