Have a contest where the winner eggifies the most rabbits. Prizes could include an Easter egg (rare passive mob egg) and Easter candy (repurposed Halloween candy) Also, holiday boxes for Easter would double as Easter baskets with various goodies with the possibility of a rare Easter egg (rare passive mob egg). For an additional challenge have about 5% of the Easter baskets guarded by a killer rabbit with better loot than the non-guarded baskets. I don't know if it is possible to hide mob eggs to find, but that would be neat too. Rare passive mobs would include the brown mooshroom, pink sheep, blue axolotl, and skeleton horse (max speed).
