You, obviously, were not paying attention to the storyline of the event. These spriggans are not easter bunnies, they're thieves. The spriggans stole the eggs, because apparently there's something about easter eggs that really attract Spriggans.
Other than that, your ideas have merit, and would make for a more enjoyable easter event. Just as long as they used the same event area music as last time. >w>
