There was a bug in which you could gain Unicorn abilities and maintain Pegasus's flight abilities (Without pegasus's combat abilities). After creating a Pegasus character you would hit "Random" enough times until you get a unicorn character. You would then gain their magic and be able to fly.
Understand that this is a bug, not a feature. So I expect it will be patched in the next update.
My time play Club Penguin was... interesting. I started playing in 2010 when I was 10, I had grown bored of it shortly after 4 months. I logged back on once, and found a strange group of penguins and I soon was quick to discover they were a part of a small, but vibrant "army" community.
It had so much depth to it, I can tell you a lot more if you request it.
It's so immersible and I just remember the glory days of the community, man I loved it so much.
