There are seven different tasks:
- Picking apples with Little My and Sniff
- Moominpappa's packing machine
- Sorting out jam jars in the basement with Snork
- Moominmamma and Moomintroll's badminton game
- Making different outfits for Ninny
- Musical game with Snufkin
- Mushroom picking with Moominmamma (locked; opens when enough other tasks are done)
After each task, Ninny becomes a little more visible. Moominmamma is involved in every assignment and gives advice during each of them.
Of all the characters in the game, only Moominmamma talks. All but one of the tasks can be accessed from the menu inside the Moominhouse, not from the Moominvalley menu, as in the previous and following Moomin computer games.
