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!
I can't tell the person this gift 
is for what it's going to be.
لا أستطيع أن أخبر مَن سأهديه بماهيّة هديّته
Denen ich damit eine Freude machen will,
kann ich das ja nicht jetzt schon stecken.
No puedo decirle a la persona
para quien es el regalo.
No se lo puedo decir
a quien le voy a hacer el regalo.
Il faut savoir garder un secret,
quand on veut offrir un cadeau.
Non posso certo dirlo apertamente
Não posso dizer o que é logo
a quem vai receber de presente...
Нельзя же спойлерить подарок тому,
кому собираешься его дарить.
