Nigga, have you forgotten she's a cartoon, a fictional character, and can't get hurt?
You go to prison over -real- children.
The reason going after real children is illegal isn't because of their looks (though they're pretty gross looking to begin with), but because their brains aren't developed.
They don't know what's going on and therefore can't consent.
That would be taking advantage of them.
Fictional kids don't even act like kids most of the time.
They often have the personalities and intelligence of adults, so they would be able to consent.
They'll be fine.
Now if you'll excuse me I'm gonna go jack it to a bunch of lines, shapes, and colors like I'm supposed to.
