Celeste features many optional collectable items to give the player an additional challenge.
Berries[edit | edit source]
Red Strawberries[edit | edit source]
Red Strawberries, also known as Red Berries, are the main collectable of Celeste. They are found in every A-Side other than Reflection and Farewell. They serve no gameplay purpose other than as an optional challenge for the player, as mentioned in the Old Site A-Side postcard, although they are required for completing some achievements and change both the pie and the characters' reactions to it at the end of the Epilogue.
Strawberry Seeds[edit | edit source]
Strawberry Seeds are sometimes required to be collected for a Red Strawberry to spawn. If you touch the ground before gathering all seeds in a room, the ones collected will move to their original positions, and you will need to start over. The Red Strawberry will spawn once all Strawberry Seeds are collected.
Winged Red Strawberries[edit | edit source]
Winged Red Strawberries are a variant of Red Strawberries. Dashing into a room containing a winged Strawberry will cause it to fly upwards, off-screen, phasing past any objects on its way, only returning once you leave the room or die. This forces the player to reach it without dashing. A winged Strawberry can still be collected while it is flying away, so dashing into it is sometimes required.
Golden Strawberries[edit | edit source]
Golden Strawberries are unlocked after beating Core B-Side and appear at the start of every chapter the player has already completed. Upon picking one up, the player is expected to finish the entire chapter without dying in order to collect it, as a death will result in both the loss of the berry and the player being teleported back to the room where they first obtained it.
Winged Golden Berry[edit | edit source]
The Winged Golden Berry is a collectable exclusive to Forsaken City A-Side. It can only be obtained by beating the chapter without dashing, as opposed to normal Golden Berries, where the challenge is not dying through the entire chapter. If the player does dash and then moves through a screen transition, the winged berry will disappear, making the player restart the chapter to attempt it again. Upon completing Forsaken City A-Side without dashing, the player will find the Winged Golden Berry floating mid-air. It can be obtained via dashing into it, though much like Winged Red Berries, it will attempt to fly away.
Moon Berry[edit | edit source]
The Moon Berry is found at the very end of Farewell, and to get it, the player has to break the final Breaker Box and then go leftwards. Doing so takes the player to a secret room with the Moon Berry at the top. It collects identically to a normal berry, though it displays "WOW" instead of the number and unlocks the WOW achievement.
Crystal Hearts[edit | edit source]
Crystal Hearts are collectables required to unlock Crystal Heart Gates. They appear in different colors, all corresponding to their alternate sides: blue in A-Sides, red in B-Sides, and gold in C-Sides.
Cassette Tapes[edit | edit source]
Main article: Cassette Tape
There is a hidden Cassette Tape in every chapter's A-side except Farewell. They can be found in special rooms featuring Cassette Blocks and an 8-bit remix of the music. Collecting a Cassette Tape will unlock that chapter's B-side, where you can find a red crystal heart.
