Operation Mayhem is a Coming Soon minigame on the Winter Island. There are 4 NPC's regarding Operation Mayhem:
Agent Kapustin
Agent Kvasov
Agent Kruglov
Agent Komarov
Agent Kapustin seems to be the leader in Operation Mayhem.
As of May 3, 2020, after the Defend Jerry's Workshop event, a message appears in the chat saying "Operation Mayhem is starting in 30 seconds! Head to the Ice Caves to take part." This appears to be a bug, as Operation Mayhem does not actually take place.
Dialogue[]
Agent Kapustin:
Hey [Player Name]!
My crew is preparing Operation Mayhem in the caves.
Don't tell anyone, it's top secret!
Agents Kvasov, Kruglov, and Komarov
The penguins are hard at work

It is a coming soon feature in SkyBlock, but little is known about it.
