Some Ideas I had for other bonus events,
Super Drops, x2 the loot and higher quality,
Happy Breeder, Faster breeding, much like the Valentines Day event,
Apex Predator, Increased alpha spawns, and alphas of other dinos, Brontos, Argents, Megas, Terror birds, bears etc etc that give helm skins of the dino you killed, terror bird helm, Shark hat! YES PLZ!
ARK Angling, Bonus items from fishing higher quality blueprints.
Super Spelunker, Increased XP and mats gained while inside caves
Fear of the Deep, Increased ocean spawns, + alpha megas
