Chapter Overview & Story Flow
Moomin: Midsummer Madness follows the Moomin family and friends through a chaotic midsummer adventure where the valley floods and the cast sets sail on an unlikely voyage. Each chapter mixes exploration, dialogue with familiar characters, and environmental puzzles, punctuated by a generous helping of mini-games. Progression is linear, but several puzzles expect you to connect very subtle clues, which is where most players get stuck.
Video Highlights:
- Full solution for the Chapter 3 Hattifattener lure puzzle
- How to grab the woodpecker using Little My's climbing ability
- Why you must talk to Mymble and read her weather newspaper to the Hattifattener
- Slingshot and machine-lever emblem matching explained step by step
| Chapter | Focus | Key Characters | Difficulty |
|---|---|---|---|
| Chapter 1 | Intro, flood, boarding the voyage | Moomin, Moominpappa | ★☆☆☆☆ |
| Chapter 2 | Exploration, early mini-games | Moomin, Snork | ★★☆☆☆ |
| Chapter 3 | Hattifattener lure puzzle | Little My, Mymble | ★★★★☆ |
| Chapter 4 | Voyage events, emblem machines | Moomin, crew | ★★★☆☆ |
| Chapter 5 | Finale and story resolution | Full cast | ★★☆☆☆ |
The game's hints start subtle and stay subtle. If a puzzle seems impossible, re-check every nearby tree, NPC, and loose item — the solution is almost always an object you walked past earlier.
Character Abilities & When to Swap
Character switching is the core mechanic that unlocks most puzzle solutions. Each friend has a niche skill, and the game rarely tells you directly who to use.
| Character | Ability | Best Used For |
|---|---|---|
| Moomin | General interaction, dialogue | Talking, carrying, basic tasks |
| Little My | Climbing trees | Fetching high items like the woodpecker |
| Mymble | Story flags, item handoffs | Weather newspaper in Chapter 3 |
Moomin
- Default exploration character
- Handles most NPC conversations
- Cannot climb trees or ledges
Little My
- Tree-climbing specialist
- Retrieved items go to shared inventory
- Essential in Chapter 3
Mymble
- Key story NPC in Chapter 3
- Provides the bad weather forecast newspaper
- Talk to her twice if stuck
Players repeatedly try to grab the woodpecker with Moomin and assume the game is bugged. It is not — switch to Little My, climb the tree, and the item drops straight into your inventory.
Chapter 3 Walkthrough: Luring the Hattifattener
Chapter 3 is the most-searched section of Moomin: Midsummer Madness for good reason. The Hattifattener puzzle chains together three separate tasks that the game never explicitly connects. Here is the full sequence.
Find the Woodpecker Tree
Locate the tree beside the area where the Hattifattener first sits. A woodpecker is perched on it. Moomin cannot reach it.
Switch to Little My
Select Little My from your character roster. She climbs the tree and retrieves the woodpecker, which enters your shared inventory.
Talk to Mymble
Speak with Mymble, Little My's sister. Ask why she is wearing a raincoat — she hands over the newspaper containing the bad weather forecast.
Read the Forecast to the Hattifattener
Use the newspaper near the Hattifattener. Storm news is what lures the creature out of its spot.
Solve the Emblem Machine
Select your slingshot, insert it into the machine with a working lever, and match the emblems: the woodpecker slot goes where noise fits, the paper item from Mymble slots into place, and the thunder emblem completes the lure. Keep the storm cloud emblem oriented correctly.
Once the emblems align correctly, the machine activates and the Hattifattener is successfully lured — and yes, the creature is described as dangerous, so do not expect to keep it as a pet no matter how cute it looks.
General Puzzle & Mini-Game Strategies
| Mini-Game Type | What It Involves | Strategy |
|---|---|---|
| Slingshot | Aiming at targets | Line up before the target moves |
| Machine levers | Rotating emblem pieces | Solve one row at a time |
| Character tasks | Climbing, fetching | Swap characters before retrying |
| Dialogue puzzles | Asking the right NPC | Exhaust every conversation option |
Universal tips that carry through every chapter:
- Talk to every NPC twice — second conversations often unlock the item or flag you need
- Check trees and high ledges first; if an item is visible but unreachable, it belongs to Little My
- Mini-games reward patience over speed; there is no fail-state penalty worth rushing for
- Keep your inventory organized — puzzle items like the woodpecker and newspaper look similar
This title keeps its hints deliberately subtle throughout. If you enjoyed the detective-style clue-hunting, Chapters 4 and 5 continue the pattern with the emblem machines introduced in Chapter 3.

FAQ
Q: How do I get the woodpecker in Moomin: Midsummer Madness?
Switch from Moomin to Little My. She is the only character who can climb the tree next to the Hattifattener's area, and the woodpecker then goes into your shared inventory.
Q: Why is Mymble wearing a raincoat in Chapter 3?
Her raincoat is a story clue. Ask her about it and she hands over a newspaper with a bad weather forecast — that newspaper is a required item for luring the Hattifattener.
Q: What goes into the emblem machine in Chapter 3?
Insert your slingshot into the machine with a working lever, then match the emblems: the noisy woodpecker, the paper item from Mymble, and the thunder emblem, while keeping the storm cloud oriented correctly.
Q: Is the Hattifattener dangerous?
Yes — the game explicitly describes the creature as dangerous, and it escapes during the sequence. It cannot be kept as a pet despite how cute it appears.
