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!
She probably wouldn't understand 
if I said "stretchy material"...
على الأرجح لن تفهمني إذا قلتُ

Se chiedessi un materiale elastico, 
non credo capirebbe cosa intendo...
Provavelmente ela não vai entender
se eu disser "material elástico"...
