I loved the special animals that spawned for the 12 days of Christmas! I hope this will be something that repeats every year in future? I have a few ideas for if it does.
It would be a bit weird to have a new 12 funny named animals every year, the server would fill up very quickly with strange beings, but it would be boring just to have the same ones every year. I was thinking that each year a new animal is added. So say for example next year we add a new animal and take off one of the old ones. Then the year after we'd add another animal, then for the remaining 11 randomly pick from all the past animals. Maybe after a few years we can start phasing out the older ones. Eventually we'd have special named versions of all the animals, but it would take many years, so we wouldn't be running out of things to do any time soon. It may also be nice to have the special animals give higher fighting skill when killed for those who don't want to collect them.
What does everyone think?
