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!
so I'd say it's just about 
as smooth as you are.
لذا أظنّها ملساء مثلك
Und daher auch ähnlich glanzvoll glatt,
wie Sie es sind, Meister Rimuru.
así que debe ser tan suave como tú.
e pare sia lucente quanto te, Grande Limur.
diria que é tão lisinho como você.
