new Float:EasterEggs[][]=

    {X, Y, Z}, 
    {X, Y, Z}, 
    {X, Y, Z}, 
    //etc.. 
}; 
new lastcoords=-1;
stock SpawnEasterEgg()
{
new randomCoord;
randomCoord = random(sizeof(EasterEggs));
while(randomCoord==lastcoords)
{
      randomCoord = random(sizeof(EasterEggs));
}
lastcoords = randomCoord;
// spawn it.
}

Edit : Are you going to spawn all of the easter eggs at one time or you will spawn them after a timer or you want just one easter egg to spawn ?
