Acute observers may have noticed something missing from Dizzy's tail so far -
I don't know if there's any reason for the tail ribbon besides colour balance and cuteness, but I'd like to know what the people involved in her design were thinking.
Personally I thought it would make sense if Dizzy put it on her tail around this time in her story in an effort to make her most obviously "monstrous" part less bad!
Maybe it's also a memento of sorts, in the case of my series for example the sash of her dress from picture 2
