In Moominsummer Madness, Snufkin briefly becomes the caretaker of twenty-four orphans after he's saved them from a rule-obsessed Park Keeper. While they give him a lot of grief, there is a pretty touching moment when the children (at the prompting of Little My) present him with a gift: A home-made tobacco pouch, filled with "raspberry leaves to smoke on Sundays." He takes it as the kind gesture it is and thanks them warmly.
At the end of the book, Moomin finds Snufkin fishing and smoking by the river, and notices that the tobacco smoke smells differently than usual:
Moomin: Have you changed to a new brand? Reminds me of raspberry leaves. Is it good? Snufkin: No. But I smoke it only on Sundays.
