The Blood Moon turns the sky crimson, changes the moon, adds red spore particles, and brings out special Blood Moon spawns.

While it is active, some wild spawns can have better shiny odds, certain evolutions become possible, and eligible defeated species can drop Blood Moon loot like bloodstone, gemstones, and related items.

Cobblemon battles can also detect bloodmoon weather during the event.

The Blue Moon adds Blue Moon battle weather and gives nearby players water-themed buffs like Night Vision, Dolphin's Grace, faster swimming, and sometimes Conduit Power in rain.

Aquatic mobs can get Water Breathing, fish or glow squid may appear near water, and light frost can show up on grass at night.

It also adds Cobblemon bonuses like extra shiny rolls, friendship boosts, and special spawn chances.

Special: Can be called by Selyn.
