Hi! I have created an addon that adds fireflies to Minecraft Bedrock Edition. But I decided to make a variation of fireflies:
1. Yellow firefly: will appear in the savannah and plains.
2. Green firefly: will appear in the taiga and in the clay biome.
3. Orange Firefly: will appear in the crimson forest and in the jungle.
4. White Firefly: will appear in the Valley of Souls.
5. Purple Firefly: !!! US GOVERNMENT DATA !!!
And in these biomes you will find them with 100% probability. Fireflies will appear in groups, that is, four fireflies in each. I also want to say that fireflies in this version of the addon will not appear in the mangrove jungle.
