Wait, if Lisa's spikes can be styled like real hair, what was with that scene on "Lisa on Ice" where her hair spikes popped the volleyball and the coach said, "Kids, that was our only ball. There won't be a team this year."? And that wasn't a non-canon episode, either. The Treehouse of Horror episodes, I understand them not sticking 100% to canon.

Yes, indirectly. The whole episode is based on the musical "Evita", in which the life of Eva Peron is sketched. The song Lisa sings is based on the song "Rainbow High" from the musical.
I think this one was banned here in Argentina cuz i haven't seen it in a looooong time man, and as an argentinian trust me, we watch more than enough simpsons every week
