Trivia
- In 2026 the event was officially named Joker's Mayhem.
- Although now generally phased out even in its seasonal variants, The Vault returned for the 2026 event as Joker's Mayhem Vault and featured the majority of presents yielding junk items such as Rubber Chicken, Chattering Teeth, Joker Toxin Filter, with the occasional drop or final loot of equipment or other past April Fools event reward items.
