Part of the opening on Hat Kid's spaceship - the ship starts dark and you restore its power early in the story. Unlocks naturally as you play; cannot be missed.
Hat Kid can sit in chairs by interacting with them. Find three different chairs and sit in each - your spaceship has several, so you can clear this in the hub without entering a level.
Badges are bought from the Badge Seller with Pons (and some are found in levels). Buy or find any badge, then equip it from the inventory/badge menu. Comes naturally within the first chapter or two.
Subscribe to any mod or custom level on the A Hat in Time Steam Workshop, then load it from the game's Mods menu. Any Workshop mod counts per the description - a small custom level is the quickest option.
The spaceship has a ridable vacuum cleaner. Find it in the hub and interact with it to hop on. Exact location in the ship not verified here - explore the rooms after the ship's power is restored.
Tied to sliding down an especially long slope during normal play. The exact slope is not verified here - see a community guide if it does not pop on its own while playing through the chapters.
You start with limited badge slots; more are earned as you progress. Once you have three slots and three badges, equip all three at once. Comes with normal story progress.
Murder on the Owl Express is an act in Battle of the Birds (Chapter 2). Search every carriage carefully and collect every clue before finishing the act. Its opposite, False Detective, needs a run with zero clues - acts can be replayed, so do one of each.
The description only says to find a secret hideout. The exact spot is not verified here - see a community guide. Exploring off the main path in the chapter hubs is the general approach.
In Subcon Forest (Chapter 3), find the large mushroom and platform your way to its top. The exact route is not verified here; climbing it is easiest once you have the hats that improve your movement.
Clear every act of Chapter 2, including any extra/time-rift Time Pieces that count toward the chapter. The chapter select screen shows which Time Pieces you are missing.
Battle of the Birds has the Conductor vs DJ Grooves rivalry, with points awarded per act depending on performance. The total accumulates across the chapter, so replay and improve acts until the combined score reaches 2000. Exact scoring rules not verified here.
The description gives no hint and the trigger is not verified here - see a community guide. Roughly 28% of players have it, so it is likely something you can stumble into, but we will not guess the exact action.
Clear every act of Chapter 1 and collect its remaining Time Pieces. Use the chapter select screen to see which ones you still need.
Clear every act/contract in Chapter 3. Some acts open up as you progress through the Snatcher's contracts, so keep revisiting the chapter until the Time Piece count is full.
Subcon Well is an act in Subcon Forest with rising water. Finish it without ever touching the water - move steadily upward and don't linger. Replay the act if you slip.
Collect every Time Piece in Chapter 4, including the different areas of the hub and the related acts. The chapter select screen tracks what is missing.
Requires the hookshot ability. Find a ceiling fan with a hook point and latch on with the hookshot. Exact location not verified here - look for fans with hook rings while exploring.
Hat Kid gets a scooter (bought/unlocked through normal progress). Find a ramp or high drop and perform a 360 flip mid-air while riding it. Exact input not verified here; experiment with jump plus directional input in the air.
Stickers are collectibles. Holographic ones are rarer variants - finding any one unlocks this. Exact source not verified here; see a community guide if it does not come naturally.
Collect every Time Piece in the game. Per community lists, the Arctic Cruise and Nyakuza Metro chapters belong to DLC - check what your 'all Time Pieces' total includes on your own copy, since the requirement is not verified here.
The description only mentions a secret food combination. Where and how to combine food is not verified here - see a community guide.
Play any Workshop level (see Unlimited Possibilities) and leave a rating for it. Do this alongside that achievement.
Nyakuza Metro is a DLC chapter (the Nyakuza Metro + Online Party DLC). Collect every Time Piece in it. The chapter's acts are reached through the metro hub.
The description implies doing something earlier or in a different order than the game intends. The exact trigger is not verified here - see a community guide.
Online Party lets several Hat Kids play together. Clear an act while you are the player in the lead. Requires the Nyakuza Metro + Online Party DLC and other players online.
Death Wish (from the Seal the Deal DLC) is a set of hard remixed challenges, each with several objectives worth stamps. Pick one Death Wish and clear every one of its objectives. Choose an easier contract for this.
Chain five homing attacks on enemies or objects without landing in between. Find a spot with several enemies or bouncy targets lined up - a crowd of foes is the easiest place to practise.
The Arctic Cruise is the Seal the Deal DLC chapter. Clear all its acts. Requires the Seal the Deal DLC.
Lava Cake is one of the peaks in Alpine Skyline (Chapter 4). Finish it without touching lava once - take it slow, memorise the route, and reset if you clip it.
Start local co-op (a second player joins as Bow Kid) and collect three Time Pieces you have not collected before. Time Pieces you already own don't count, so leave a few for a co-op session - or start a new save file.
The Big Parade is an act in Battle of the Birds. Finish it without falling off into the crowd below. Learn the act first, then do a careful run.
The opposite of True Detective: play Murder on the Owl Express and finish it without picking up a single clue. Acts can be replayed, so do this as its own run.

Collect 30 stickers inside the Nyakuza Metro DLC chapter. Explore every area of the metro hub and its acts.
Join an Online Party session with 10+ players total. Requires the Nyakuza Metro + Online Party DLC. Busy public sessions or community events make this easier.
Train Rush is a timed act in Battle of the Birds. Finish it without dying and without grabbing any of the time bonuses - so the route must be fast enough on base time alone. Practise the route first.
Equip the One-Hit Hero badge (you die in one hit) and defeat any boss. Choose the boss you know best - an early-chapter one is usually the safest pick.
Dead Bird Studio is an act in Battle of the Birds with guards. Finish it without being spotted once. Move slowly, learn patrol routes, and restart if you are seen.
Collect ten Time Pieces while in an active Online Party session. Needs the Nyakuza Metro + Online Party DLC.

Ship Shape is an act in The Arctic Cruise (Seal the Deal DLC). Complete its tasks without upsetting the Captain - in practice, do not fail or let tasks lapse. Requires the Seal the Deal DLC.
Some Steam Workshop levels award Mod Rift Tokens. Play Workshop maps that hand them out until you have 30. Short, well-rated token levels are the fastest route.
Earn every Death Wish stamp - the hardest achievement in the game, with only ~2% of players. Covers every objective in every Death Wish contract. Requires the Seal the Deal DLC.
