Every chapter has one Golden Strawberry, and they're considered one of the biggest challenges in the entire game. 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. Golden Strawberries are special collectibles that can be unlocked when the player has completed Core B-Side. 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. Winged Strawberries lose their wings if the player touches/collects them. Winged Strawberries will respawn if the player retries the room. Winged Strawberries are an uncommon type of Red Strawberries that fly away after a dash is used. If the player dies after unlocking the berry, it will remain. Collecting all seeds in a room without touching the ground causes the seeds to combine into a Red Strawberry. Collected seeds respawn once the player touches the ground. Strawberry Seeds are small yellow-green collectibles that are scattered around a single room. Getting a 1UP will unlock its corresponding achievement, but this scoring has no other effects. Collecting multiple strawberries at once will increase the score to 2000, then 3000, then 4000, then 5000, before then giving a 1UP. When collecting strawberries, they will give a score of 1000. It is possible to stop berries from collecting, which can allow the player to start a chain of strawberries. Upon collecting, it follows the player unless they remain on safe ground for a small amount of time. They appear in many rooms, including hidden areas that normally aren't required to progress. They appear in every A-Side, with the exception of Chapter 6: Reflection, and the DLC chapter, Farewell.

Red Strawberries are the most common berry in the game. The amount of collected Strawberries also affect which ending the player will get in Epilogue. Collecting 175 strawberries however, unlocks the "Impress Your Friends" achievement.

They don't serve any sort of purpose apart from giving the player an extra challenge and to fill up stats. Strawberries are basic collectibles that can be found in every chapter and they appear in several different types.
