Tensura Nikki: Tensei shitara Slime Datta Ken season 1 episode 10
Episode title: Snow Blankets the City of Monsters
Winter has arrived in Tempest, and so much snow has fallen that its residents can't open their doors until it's shoveled away. But there are at least three like minds there who are finding it hard to resist their childlike urges to dive into the fresh snow: Rimuru, Milim, and Shion. Thus the work begins all around town to shovel Tempest out of the deep snow. Youm objects to being asked to help since he isn't even a citizen, but when he's given the choice between shoveling snow and training with Hakuro, he eagerly grabs the shovel and gets to work.
