To find the three flowers in Blox Fruits, follow these steps:
Red Flowers bloom during the day. Look for them between two buildings, on an island with a towering structure, on an island with a bridge, in a forest of mushrooms and flowers, or under a pink-orange flower. Keep your eyes peeled as they blend well with the surroundings.
Blue Flowers appear at night. Search in grassy patches on islands, inside caves, or on islands with spikes next to a tree. The darkness makes them stand out, so they’re easier to spot at nighttime.
Yellow Flowers are different; you get them by defeating any NPC. Once an NPC is beaten, they will drop a yellow flower. This makes it the easiest flower to obtain but requires some combat skills.
After collecting all three flowers, head back to the Alchemist to complete your quest. This will grant you Race V2, an essential upgrade for your character in Blox Fruits. Enjoy your new abilities and continue your adventure!
