Breath of the Wild is a game where Link has to brush his teeth. Nintendo cancelled all the other games just for this final buildup. This is the only Zelda game to ever exist. Shame.
Long ago there were 4 divine teeths, with 4 people who brushed them. But then the Cavity Ganon came along, to make all of the teeth have cavities. Link tried defeating the Cavity Ganon, but ultimately got struck down, and was sealed off. Link wakes up 100 years later, only to see the Cavity Ganon still giving hyrule cavities, however Link has no previous memory of this. Using his Sheikah Toothpaste, and Parabrusher, he must save hyrule from the dangers of Cavities.
