Um, Actually

In Snowdin, we are introduced to the multicolor tile puzzle by Papyrus. Each colored tile has a different function, and have complicated interactions, as explained by Papyrus. If the player understands Papyrus' explanation, Papyrus will activate the puzzle, only for it to generate an extremely simple layout. If the player doesn't understand it, Papyrus will explain the puzzle again, only to fumble on the details. If the player insist in being confused, Papyrus won't activate the puzzle, allowing the user to skip it. In either situation, the complicated function and interaction of the tiles was completely insignificant to the player.
