I find it weird that so many people here say "so and so shouldn't be added to Morning Musume because their singing and dancing are up to par so they should be put into eggs instead" as if everyone in The 9ki 10ki 11ki were Riho's when they joined. Even Riho wasn't perfect when she got in the group. Haruna couldn't dance, Erina couldn't sing, Kanon couldn't do either... Most of 9th gen was chosen for personality alone and 10th gen were chosen more for talent, but that wasn't even enough since Oda had to be added for singing ability. So saying Cuca or anyone else should be added to eggs because her singing and dancing isn't good enough just seems like a weak argument.
I know I have a Cuca avatar so it might seem like a bais but it's not just her that people say this for. I'd be over the moon if Cuca made it into the eggs because its better than not making it past round 3. What doesn't make sense to me is that argument about not being talented enough as if everyone in Morning Musume were aces when they were added. Tsunku sometimes even prefers unpolished girls (Aika, Konkon).
