Why do blueberry mulberry go crazy when eating sugar?

Eating sugar will drive you crazy. There are two sets and three sets.

Sans (Chinese name: Shanxi) is a character in the game Undertale (Chinese name: undertale).

Sans, the brother of papyrus, made his debut in the forest outside Ding Town, Si Nuo. Depending on the player's actions, he will become your trusted friend or a terrible opponent like a hero.

On Wikipedia? In the poll of Undertale website (Title: Which role do you like best), Sans voted 32. 19%, which is about 1/3 of the total votes.

Personality:

Sans's laziness is well known, and sleeping at work is common. He likes to play tricks on his brother with puns about bones. He is generous and very comforting, but sometimes, especially when he is angry, he becomes serious, which may imply that his usual improvisation is just a cover-up.

He is very keen, and his reaction is particularly different with the different actions of the players. He can feel the change in the timeline. He said he hated making promises, because he would break his promise with Torre and hurt mankind on the route of slaughter.

His laziness was also mentioned in the last battle of the holocaust route: he knew that the reset of the timeline would make all his efforts go up in smoke, and he knew that everything he did was in vain. Even if he returns to the ground, he will eventually be "brought" back to the ground. Maybe this is just an excuse for his laziness.
