He is also quite kind to others, such as the protagonist will never be killed by him; instead, Sans captures the protagonist if the protagonist reaches one health bar. Sans enjoys tacos (and burritos) instead of spaghetti (Italian food being swapped with Mexican). he likes to say "MWEH HEH HEH". He still enjoys making puns. He also likes riddles instead of puzzles.
