Lost and Found Co Side Quests: KOZ Walkthroughs, Hidden Items, and Search Tips

What Counts as a Side Quest in Lost and Found Co

Lost and Found Co. is a hidden object adventure built around small objects tucked into crowded, layered scenes. The main Story Cases push the plot forward, but a large chunk of the content sits off to the side — and that's usually where players get stuck.

According to the beginner breakdown from Casual Game Guides, the game separates its content into four buckets:

• Story Cases — the main adventure path
• Requests — side jobs that function like optional missions
• Optional objectives — extra goals inside a level you're already playing
• Juju — hidden helpers disguised as ordinary objects that grant extra hints later

That structure explains why Lost and Found Co side quests feel so different from one another. Some are quick in-level favors, like the icy treat request in the first level. Others, like the KOZ quests, are sprawling multi-part hunts across an entire stage with a dozen or more hidden targets.

The practical takeaway: clear the main objective first, then loop back for optional goals once you know the layout of a room. Trying to do both at once is how you end up half-searching five areas and remembering none of them.

The KOZ Side Quests Are the Hardest Optional Content

The Into Indie Games KOZ side quest walkthrough (published March 10, 2026) describes these as long and very hard, with items hidden cleverly across large stages. Two of them — Waiting for a Bite and Apartment Apocalypse — are the ones most players search for help with.

Waiting for a Bite: where the key items are

This quest spreads its targets across a mountain, a harbor, and several shops. The verified locations from that walkthrough:

• Ceremonial Master — top of the mountain in the north of the stage
• Ship Blueprint — second floor of the sushi shop, near the shark with a pink ribbon
• Lantern — on the lighthouse on the left side of the mountain
• Special ship part — in the ship shed in the bottom left with the blue sign, above the sink
• Master Gear — inside the shop next to the sushi shop, third floor near the gears
• Bucket of Red — on the boat with the laughing man on the right side
• Final part — in the house just below the mountain, near the green watering can, on top of the black bird's head

Other targets include yellow flowers hidden behind trees at the bottom left of the mountain, a hearing cone below a sink, a green substance near seaweed on the top-left island, a fireworks ball near barrels and a tennis racket, a Moonlight orb on the second floor of the second ship shed near the planet figure, a story book in a green bag near a kid, a painting in a first-floor bathroom, red bait below cat figures in the third ship shed, a fishing rod in the mouth of the giant fish mountain, a victory flag near cats at the harbor, and a festival plan on a boat with a scooter behind the ship shed.

Apartment Apocalypse: matching characters to objects

This stage is big enough that the hints do most of the work for you. Each target belongs to a named character, so the fastest approach is to locate the character first and then scan their immediate surroundings.

• Gamer dude — near the convenience store on the right; his girlfriend pillow is in the room near the motorbike by the bed, and his green figure sits near the pots in the plant-filled green apartment
• Lover girl — room with the pink door; the heart diary is near the heart wrappers, and the ballet shoe hides behind the penguin holding cards in the door with ice on it
• Hackerman — room with the black door near some boxes
• Data chip — inside the lover girl's house on a snack table
• Dude note — in the purple room under the lamp
• Nako-chan — outside with cats; the trophy is near the refrigerator by the N27 door, and the cat pillow is on the roof at the top left
• Cool dog — standing near the bike; the biker helmet is in the dragon room near the fridge, and the spiky jacket is near the shelf in the garden house
• Winter Girl — outside the penguin room; her cap is in a microwave in the lover girl's house, and the popsicle is on the gamer dude's desk with pencils
• Mafia boss — in the dragon room; the Snake Cane is outside near the orange tree, and the fortune snake appears when you click the toilet in the simple house next to the plant house
• Die-hard fangirl — outside the purple room; the purple book is near the woman outside the flats on the left
• Invitation card — gamer dude's room, in a basket with letters
• Plant girl — in the vegetable garden; the watering can is among the yellow flowers near stray cats in front of the apartment, and the cactus is on a stool in the biker's house
• Minimalist — next to the police station; the Minimalist Slate is below the wardrobe in the lover girl's house, and the odd doll is between the rabbit dolls
• Iron Guy — on the rooftop; clicking him gives you an Instapix

Playtime at Kenta's is the easier one

Into Indie Games rates this as a normal-difficulty side quest, though it still trips people up. The chain starts with six Kemenzetter figures:

• Rhino — behind the transparent blue box of colored pens near the socks basket
• Bull — behind the television
• Beetle — behind the pillow
• Dragon — near the video game console
• Leopard — under the green book on the desk
• Sixth figure — under the wall-mounted figure shelf

Finding all six lets you move around the house to locate Kenta, who is in the laundry room behind the blue door. From there the quest continues with clothing items: a scarf above the black shelf in the kitchen, underpants in the top-right toilet, an oversized jacket near Kenta's bed, a towel under the two portraits of old people, a sock near the cat in the garden through the green door, a sleep mask over a calendar in the lounge, a multipurpose rag left of the television, a purple coin purse on the lavender plant, a red hero scarf in a cardboard box, a brand new shirt on the chair, a yellow scarf under the witch's hat, and a favorite jacket behind the pillar near the garden door.

Smaller Side Quests, Requests, and Known Snags

Not every optional job is a marathon. The icy treat request in the first level is a good example of how layered these can be. In a Steam Community discussion thread, one player described the solution as clicking a blue, grinder-like machine on a small table to get a bowl of shaved ice, then continuing to click the bowl until a character collects it. A later reply in the same thread notes the quest only completes once you pour sauce on top from one of the four bottles on the counter.

The walkthrough hub on Into Indie Games also references a Runaway Foxes side quest in the early chapters, plus Missing Meow, My Summer Memories, and The Accursed Antique Shop content covered alongside the Chapters 8–9 main path. Fangtastic Feast has its own optional brewing task involving tomato sauce, which shows up repeatedly in Steam discussions as a sticking point.

One community-reported bug is worth flagging: a Steam guide covering the June 24, 2026 update warns that triggering a shuriken on the tower before accepting that mission may stop it from counting. The guide's advice is to talk to the NPC at the start of the stage. Treat that as a player report rather than a confirmed fix status.

How to Clear Optional Objectives Without Wasting Hints

Casual Game Guides makes a point that applies to every side quest in the game: the answer is rarely clicking faster. Break each scene into layers — skyline and hanging props first, then shelves and counters, then floor clutter. Clear one zone before moving to the next, and switch floors as soon as furniture starts overlapping.

Two objective types matter here. Obscured targets are hidden inside or behind something clickable, so opening the prop is the actual first step. Quest targets unlock additional targets after you find them, which means a room isn't finished just because one chain item vanished.

Juju are your safety net. Don't spend them the moment a room gets annoying — finish a broad sweep first, then use a hint when you're down to one stubborn item and need a direction rather than a solution. Catching Juju gives you extra hints for later hunts, so grabbing them early pays off across the whole game.

Finally, if a quest objective seems to have vanished, check the To-do UI. The October 14 patch notes for version 1.2.1 list a fix for not being able to open the To-do UI after quest unlocks, along with a fix for a slime objective in Fangtastic Feast that wasn't displaying correctly when re-entering the stage. If you're on an older build, updating may resolve what looks like a missing objective. The Lost and Found Co. Steam hub is where those patch notes and player-made objective lists are posted.

FAQ

How many Lost and Found Co side quests are there? There's no verified official count. Community guides catalog them by chapter and by stage, and the Steam guide "All Main and Optional Objectives" by tullybunny is the most direct attempt at a full list. The number has also grown with updates, so any fixed total goes stale quickly.

Which side quests are the hardest? The KOZ quests — Waiting for a Bite and Apartment Apocalypse — are consistently described as the longest and toughest, because their targets are scattered across entire multi-zone stages rather than a single room.

Do optional objectives matter for achievements? Steam guide authors list main and optional objectives together when describing achievement completion, so clearing them appears to be part of full completion. Juju collecting is separate and rewards you with extra hints.

Why can't I find the last item in a Lost and Found Co side quest? Most misses come from props that need an extra click before the real target appears — shelf lips, drawers, boxes, window frames, and trays. Zoom in, pan across packed areas, and check whether a clue is pointing at a container rather than an object.
