You see a cake golem.
Notes
Their bodies decay a lot faster than other bodies, approx 1 minute.
Cake golems will simultaneously spawn in various locations in Thais, Carlin, Edron, Darashia and Liberty Bay, approximately on the hour after server save of the event (CEST), and respawn every hour after that. On Antica, 21 February 2022 they spawned at 12:04 CEST.
