I've found all but the Quack and MP3 ones so far.
Ah that's goodA quote from Jamie/Zr388 from Mumble:
One person has already been banned for ruining the event. If you are going to sell eggs, give away hints, give away eggs, or ruin the event for other people when there is actual effort going in for searching for them, then I am not afraid to give an infraction or suspend the account until the event is over. Happy Easter!
i think i know what the first clue is hinting at
I just can't find the mp3 one...
