Whenever she opened her eyes wide in the early phases, they looked just like 2D's. If you want examples, check Jump The Gut, the end of 19-2000, and there's this bit in DARE where all her hair is blown back and you can see her eyes for a second. Except they look like 2D's. :V
I always wondered how she got that haircut. Actually a good way to get gum out of your hair is to stick your head in a freezer for a bit. Wait till the gum freezes, then it'll break right off. Although sticking your head in a freezer is not usually fun.
