- Annoying Dog: Toby Fox's signature 'Annoying Dog' makes several cameo appearances, often in humorous and unexpected ways. Look for him in unlikely places or listen for his distinctive bark.
- Fourth Wall Breaks: Deltarune frequently breaks the fourth wall, acknowledging the player's presence and choices. Pay attention to dialogue that seems to address you directly.
- Pop Culture Nods: From anime references to classic RPG tropes, Deltarune sprinkles in various pop culture nods. Some are subtle, while others are overt.
- Hidden Dialogue: Interact with every object and NPC multiple times. Sometimes, unique dialogue or hidden interactions only appear after repeated attempts or specific conditions are met.
Exploring every corner and interacting with everything is the best way to uncover these delightful secrets. They often provide comedic relief or deeper lore insights.
