Just like when the wetlands pack lacked the pelican which would have been so perfect for it.There is really no reason the monitor couldn't have been an American Flamingo instead.
Equal level of "clone" but representing a bird in an area with none, while the monitor is a monitor in an area where we already got one.
And in the end birds are more important.
That simple switch of clones for the pack would have made it much more appealing to me.
