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!
You'll blow this entire area off 
the map! Promise, all right?
!ستمسحين هذه المنطقة برمّتها عن الخارطة

Tu pulvériserais toute la région.
Promets-le-moi, OK ?

Afinal, você faria tudo aqui
ir pelos ares! Promete, então?
Иначе от озера пшик останется!
А ну обещай.
