What happens after you get 50,000 hero points to beat the chapter after Doc Ock?


Oh,and people have discovered this secret gate that could lead to the underground sewers where you can possibly fight Lizard....I found the gate and it looks rather conivincing that you can go through it...but fighting Lizard is just speculation and rumors.

So does anyone know what happens when you get 50000 points and how to unlock the gates to go underground?
