One day, when Shuna and Shion are fighting over Rimuru's squishy slime body as usual, Rimuru comes up with the idea to make a cushion in the shape of his slime form. He travels around Tempest to see if his friends know of any good materials he can use, and he learns that a special type of sand found along a lake shore in the forest is exactly what he's looking for. So he sets out to collect some sand... but a monster is waiting for him by the lake!
Looks like this is the lake 
Garm was talking about.
يبدو أنّ هذه هي البحيرة التي كان غارم
يتحدّث عنها
Das ist also der See,
von dem Garm gesprochen hatte.
Parece el lago del que hablaba Garm.
Parece el lago del que hablaba Garm.
Voilà donc le lac
dont Garm me parlait…
Quindi questo è il lago di cui mi parlava Garm.
Parece que é esse o lago
de que Garm falou.
Похоже, Гарм про это озеро говорил.
