What is Moomin: Midsummer Madness?
Moomin: Midsummer Madness: point-and-click with Moomintroll and Little My, a flood, and a floating theatre.
Moomin: Midsummer Madness is a Point-and-click adventure · cozy puzzle by Crossbridge Game Studios, published by Shochiku (Steam app 4463520). Midsummer is right around the corner in Moominvalley, when a sudden flood sets the Moomins adrift. Join Tove Jansson’s Moominfamily aboard a mysterious floating theatre.
A point-and-click adventure starring Moomintroll and Little My. Hand-painted scenes, light puzzles, mini-games, and a built-in hint system. Inspired by Tove Jansson’s novel Moominsummer Madness.
This Moomin: Midsummer Madness wiki maps the six-chapter flood-and-theatre story onto switchable characters, inventory combos, and minigames (some offer Skip). The Moomin: Midsummer Madness guides cover the first hour, the haunted theater, and the 12 Steam achievements. It is not a Roblox game and not the unrelated Steam title Midsummer Madness. A second Moomin: Midsummer Madness wiki pass should still match Steam app 4463520. Use a Moomin: Midsummer Madness guide when the next item, character, or minigame is the blocker.

Moomin: Midsummer Madness Guides
Start with a **Moomin: Midsummer Madness guide**, then use this **Moomin: Midsummer Madness wiki** when a character, item, or location needs a lookup.
Moomin: Midsummer Madness Beginner Guide
The first minutes are a click loop: look, talk, switch, take, combine, then use. Do not hunt a combat menu that does not exist.
- 1
Read the notebook
Current goals sit in the notebook. If you feel lost, open it before you wander.
Moomintroll and Little My both record objectives.
- 2
Switch characters
Little My climbs, squeezes, and rides tight props. Moomintroll handles most adult-height clicks.
Leave ladders in place before you swap.
- 3
Combine vs use
Two inventory items combine in the bag. Using an item on scenery is a different click.
Paintbrush + tablecloth is a combo, not a hotspot.
- 4
Try a hint, then Skip
The built-in hint keeps the story cozy. Minigames may offer Skip if you only want plot.
Skip is not the puzzle solution; it only continues the chapter.
- 5
Open the walkthrough
When a chapter stalls, jump to the six-chapter route instead of replaying every hotspot.
Chapter 3 (theater) is the usual public stuck point.
Quick tips
Tip 2
There are no redeem codes. This wiki has no /codes page.
Tip 3
There is no official Discord invite on SteamDB social links. Use Steam discussions and Shochiku socials.
Tip 4
Inventory combine and “use on scenery” are different clicks. Switch to Little My for climbs, boxes, and tight gaps.
Tip 5
Several minigames show Skip. Skip continues the story; it is not the puzzle solution.
Moomin: Midsummer Madness Chapter Layers
Read each layer by the bottleneck it removes: outfits, underwater breakfast, theater weather, park errands, slippers, disguise.
Ch.1 bark boat
Snorkmaiden’s outfit, then the model-boat board.
Ch.2 flooded house
Breakfast dive, attic mazes, bun launches.
Ch.3 haunted theater
Storm for the Hattifattener, barometer, sun ropes.
Ch.4 park night
Children, cough syrup, poster for Snufkin.
Ch.5–6 close
Yellow slippers, then the police-chief disguise.
Switch rule
If a hotspot is too high or too small, swap to Little My before you hunt a new item.
