This Moomin: Midsummer Madness locations wiki is a screen list: valley pond, Moominhouse (dry then flooded), attic, floating theater (stage, backstage, dressing rooms, hatch, rafters), park, well, Fillyjonk’s house, props room. Verified November 15, 2026. You can usually walk back inside the current chapter; treat closed doors as chapter gates, not bugs.
Water changes how rooms connect. The same house has an upstairs breakfast layer and a helmet-dive layer. The theater has a stage you must re-check after every scenery-machine change.
| Place | Chapter | Why you go |
|---|---|---|
| Valley pond / house exterior | 1 | Rope, ring, dress ingredients, bird |
| Moominhouse interior | 2 | Breakfast, hole, stairs |
| Flooded lower house | 2 | Crab cupboard, kitchen tin |
| Attic | 2 / 5 | Mazes, binoculars, spider repairs |
| Theater exterior | 3 | Log, matches, Mymble newspaper |
| Stage / backstage / dressing | 3–5 | Locks, scenery, performance |
| Hatch / underwater theater | 3 / 5 | Barometer, music-box shell |
| Rafters | 3 | Sun knots |
| Park / booth / ponds | 4 | Children, keeper, flowers |
| Well / hay / Fillyjonk | 4 | Gears, honey, syrup, crow nest |
| Props room | 5 | Admirer chain |
| Late valley / policeman pond | 6 | Disguise pieces |
Chapter 1 is exterior: building with drainpipe, pond with Moomintroll, left screens for paint and tablecloth, tree with flower, postbox bird. The model-boat board is its own UI, not a new map. After the flood, Chapter 2 uses the same house from the inside: bedroom, downstairs talk, floor hole, front door to Mymble, flooded stair, kitchen through the right-hand lower door, attic via upstairs.
The garden swing for Garden Harmony is a house-exterior extra, not a story gate. Haystack hops for Summer Bed sit with Chapter 4 hay, not the theater. Mark those as extras on the achievements page rather than blocking the route here.

Approach by log. Interior: stage (tub fabric, shell/Hattifattener, hatch, later chests), backstage scenery machine, dressing rooms and wig lock, striped magician box as a shortcut, upstairs sacks and props door in Chapter 5, underwater volume under the hatch. Re-enter the stage after every machine change. Fan under the hatch is both a story switch and Little My’s elevator.
This is the building named in store copy as the curious old theatre caught in the flood. Official art shows Moominhouse and the floating theater as separate silhouettes — do not merge them into one map in your notes.

Matched by build plan, shared topics, and guide progression — not random related links.
Chapter 4 park: pond with reed, tree bag with mustard, berries, keeper, booth (paint, hose, blue bottle, book), left pond frog, hollow tree, Fillyjonk’s doorbell to the left, well near the start, hay and scarecrow, campfire hand-in. Chapter 6 returns to a valley mix: tree bag harmonica, bushes coins, living-room climb, kitchen stove, policeman pond, dark back room, chimney path from earlier poster work.
Nintendo Switch play is the same geography with touch prompts. Steam and Switch saves do not transfer just because the rooms look identical.
Inside a chapter, screens stay available until the notebook moves you. Across chapters, some theater rooms reopen in Chapter 5 (props, underwater shell). Do not expect a fully free overworld like an MMO. If a door ignores clicks, you are missing the chapter item, not a fast-travel unlock.
Next: pin the hotspot to an object on items or a person on characters. A Moomin: Midsummer Madness locations pass should also mark “same building, new layer.” The flooded staircase is still Moominhouse, just with a bowl helmet. The hatch is still the theater, just underwater. The props room is still the theater, just upstairs after Emma’s key. Players who draw a 2D map with one room per name will miss those layers and think a door vanished. Chapter 5 reuses theater geography on purpose: the lion, the sacks, the suitcase, and the underwater shell are not a new island. Chapter 6’s policeman pond is valley-side, closer to the house than to the floating stage. If you are hunting jellyfish for Squish Squash!, dive where jellyfish actually spawn — recaps point at underwater theater paths, not the Chapter 1 pond. Nintendo’s warning about Switch vs Switch 2 extra content is a store/legal note, not a hidden seventh map in this wiki.
Next: run the matching chapter on the walkthrough, or unstick the theater with Chapter 3.

Treat later dives as theater hatch / Chapter 5 shell unless your notebook says otherwise.
