After Toriel was taken away from alphys lab to get juiced after turning into a Blueberry, there passed two hours before you saw your goat mother again She wasn't so bloated as a Blueberry... But she has a thick and obese shape now, it means that theres a lot of Blueberry juice inside of her... well, better than nothing Plus, alphas recommend that Toriel will wear just a tracksuits or anyway the same elastic materials on other clothes, and wear only open shoes if she wants

Toriel: Oh... I don't feel so good... I'm so huge and bloated...
