Collectibles

Celeste features a variety of collectibles that are scattered around its chapters. Many of them serve different purposes and some of them can only be found in specific places, adding for an extra challenge for players who are willing to conquer it.

## Strawberries

Strawberries are basic collectibles that can be found in every chapter and they appear in several different types. They don't serve any sort of purpose apart from giving the player an extra challenge and to fill up stats. Collecting 175 strawberries however, unlocks the "Impress Your Friends" achievement. The amount of collected Strawberries also affect which ending the player will get in Epilogue.

### Red Strawberry

Red Strawberries are the most common berry in the game. They appear in every A-Side, with the exception of Chapter 6: Reflection, and the DLC chapter, Farewell. They appear in many rooms, including hidden areas that normally aren't required to progress. Upon collecting, it follows the player unless they remain on safe ground for a small amount of time. It is possible to stop berries from collecting, which can allow the player to start a chain of strawberries. When collecting strawberries, they will give a score of 1000. Collecting multiple strawberries at once will increase the score to 2000, then 3000, then 4000, then 5000, before then giving a 1UP. Getting a 1UP will unlock its corresponding achievement, but this scoring has no other effects.

#### Strawberry Seeds

Strawberry Seeds are small yellow-green collectibles that are scattered around a single room. Collected seeds respawn once the player touches the ground. Collecting all seeds in a room without touching the ground causes the seeds to combine into a Red Strawberry. If the player dies after unlocking the berry, it will remain. These strawberry seeds are only found in chapters 2, 4, and 5.

### Winged Strawberry

 Winged Strawberries are an uncommon type of Red Strawberries that fly away after a dash is used. Winged Strawberries will respawn if the player retries the room. Winged Strawberries lose their wings if the player touches/collects them. Most of the time, these strawberries are obtainable only by completing the room without dashing, but some require a dash to grab them before they fly away.

### Golden Strawberry

Golden Strawberries are special collectibles that can be unlocked when the player has completed Core B-Side. They appear only in chapters that have been completed before, and in order to collect them, the player has to take them to the end of the level in without dying once. Every chapter has one Golden Strawberry, and they're considered one of the biggest challenges in the entire game. Golden Strawberries can only be collected if the player grabs the Crystal Heart in B-Sides and C-Sides, or if they get to a room that triggers its collection in the A-Sides. If the player dies while carrying a Golden Strawberry, they will be taken back to the place where the berry normally appears.

* A-Side collection rooms:
	+ Forsaken City: Final room (cutscene entry not required)
	+ Old Site: Final room of Intervention (cutscene entry not required)
	+ Celestial Resort: Final room (cutscene entry required)
	+ Golden Ridge: Final room (cutscene entry not required)
	+ Mirror Temple: Final room (cutscene entry not required, Theo Crystal not required)
	+ Reflection: Final room of Rock Bottom (cutscene entry not required)
	+ Summit: Final room, final checkpoint (collected after the final set of spikes, cutscene entry not required)
	+ Core: Final room (Crystal Heart not required)

### Winged Golden Strawberry

 The Winged Golden Strawberry is a hidden secret that can only be found at the end of Chapter 1A if the player has completed the entire chapter without dashing even once. If the player enters a screen transition after using a dash to complete a room, the berry will disappear (this can be avoided by dying after accidentally using a dash). Completing the chapter without dashing takes advantage of obscure techniques such as spike jumping, neutral jumping, etc. (more explained in Moves). Unlike other Golden Strawberries, the player isn't required to complete everything without dying.

### Moon Berry

**I tried to warn you.**

This section contains spoilers for the Moon Berry and Chapter 9. Do not read the following section if you wish to avoid spoilers for the Moon Berry and Chapter 9.

 The Moon Berry is a hidden collectible found at the very end of Chapter 9: Farewell. It's found in the last sub-chapter, where the player has to take an alternative path after destroying the lightning source. It takes the player to a secret area, which is an extra challenge for players who have already beaten the chapter. It behaves very similarly to a normal berry, however upon collecting, it unlocks the "Wow" achievement.

## Crystal Hearts

     Crystal Hearts are collectibles that can be found in every chapter. They appear in different colors which resemble the Alternate Side the player has played. There are 24 total Crystal Hearts, and a gray fake Crystal Heart that can be found right before the Event Horizon sub-chapter of Farewell. Red and Golden Crystal Hearts appear at the end of their corresponding B-Sides and C-Sides, while Blue Crystal Hearts are hidden and require the player to solve a puzzle or find a secret area (with the exception being Chapter 8: Core). Colors vary depending on the type of chapter you're playing:

Crystal Hearts are required in order to unlock certain areas in the game. Their amount is different depending on the area a player is trying to unlock, regardless of the color of them:

* Core A-Side: at least 4 Crystal Hearts
* Core B-Side: 15 Crystal Hearts (All Crystal Hearts before it.)
* Core C-Side: 23 Crystal Hearts (All Crystal Hearts before it.)
* Farewell (Event Horizon): 15 Crystal Hearts (skippable, see Chapter 9: Farewell for more details)

## Cassettes

 Cassettes are collectibles that can be found in every A-Side in the game, with the exception being Chapter 9. Cassettes appear in rooms that are built around colored Rhythm Blocks that the player has to time to the music in order to progress. Collecting them unlocks the B-Side, which is a more difficult version of the regular chapter. Although Cassettes are optional collectibles, finding them is required in order to gain every Crystal Heart in the game.

Upon collecting a Cassette, a preview of the B-Side music is played, and after pressing a key, the player is transported to the spawn point of the room.

## Trivia

* There's a lot of very interesting early concept ideas from the developer stream, where Maddy Thorson and Noel Berry discussed about a lot of ideas that were changed over time or ideas that were scrapped or replaced with something else in the official version:
	+ Before Crystal Hearts were added, there were black heart pieces that appeared in their place and they filled a black heart shape upon collection, which could eventually unlock Core and other areas.
	+ When Strawberry Seeds were being created, their appearance was being changed a lot, and at first they used to be gem pieces or music notes, that would eventually unlock the B-Sides (back then named Remixes) upon collection. Once actual Cassettes were added, the idea of obtaining them was made much simplier, and shards were changed into seeds that would unlock Red Strawberries upon collecting.
	+ There were journal pages that would explain lore regarding the Celeste Mountain, and the player would be required to take them all to an NPC who would decipher them. The idea never made it, as it might have ruined the mysterious feeling of the mountain.
* If you take the Golden Strawberry into the Moon Berry room in Chapter 9, it will detach from the player and wait at the next spawn point, as there's a forced death spot. Once respawning, the player would be able to grab the berry again.
* If you manage to chain 6 strawberries, the "score" sprite will increase up to an 1-UP, unlocking an achievement.
	+ Golden Strawberries also have their own 1-UP sound, similar to their own collection noise.
