Something's a little off here...
Gaster always dressed and undressed them so they're used to people taking their gowns on and off. Sans in particular since he spent a lot more time in and out of the tube than Papyrus did.
We've actually already seen the book. Or at least, one copy of it~
这里有些东西让人有些不舒服…（？）
Gaster经常帮他们穿脱衣服所以他们习惯了有人帮他们穿脱长袍。Sans尤甚因为他比Papyrus更经常进出培养管。
我们早就见过那本书了。或者至少，是它的一个副本~
顺便Asgore：you can trust me i'm an emotionally healthy man, here put on my dead kids' clothes
你们要相信我是个心理正常的男人，来把我死去孩子的衣服穿上
