Where is the 120th star and how do you get it?

There's no way that we could possibly know which star on your saved game is teh 120th, because we have no clue of what order you collected the stars in. Try collecting 100 coins on the levels that you havent already done so on, because many of the hard-to-get stars are gotten that way.

The stars don't have any order after you get 70 stars.

The 120'th star could be anywhere depending on what other stars you got.

You could do what the others say to do. Also, try talking to toad and catching the bunny by Bowser's lava land.

What star don't you have.

I can't answer your question otherwise.

You have to tell us what stars you already have.

Yeah there is no order after you get 70!! You should use a walkthrough that tells you where every star is! =)

Well, I wouldn't know what stars u already have, but I'll tell u about a star that most people don't know about.
Go to Princess Peach's Secret Slide. There r 2 stars on this course. U know how 2 get one but 2 get the other, u will need 2 make it down the slide in less than 21 seconds. Sounds impossible, but no it a'int. This is what u do. Run down the slide and as you're sliding, stay on the right side of the wall, if it works, you'll bumb into the wall as it starts 2 turn left, then you'll start sliding backwards. When the walls end, before u start sliding on the steep parts of the slide, jump. If it works, you'll be standing on the slide. Then quickly run towards the barricade that keep u on the slide on the left-hand side of the screen going towards u, (assuming u didn't mess with the camera angle when you stopped sliding), get on the barricade, and do either a long jump or jump and push B 2 do a dive 2 make it 2 the structure below. Then quickly get up (if u hurt yourself) and then run towards where u can see the slide again, jump down, and slide down. If u make it in less than 21 seconds, a star will appear as soon as u cross the finish line. Get that star and u will have 120 stars. (If u didn't already get that one.) This sounds hard, but you'll eventually get it. Hopefully this helps, and if it does work and u get 120 stars, go 2 the last level and beat Bowser in the sky again and he will say something different.

Inside the castle go on the mat with the sub press x twice and look up and fly to unlock the boxes collect 8 red coins and you will get a star

I know exactly what start he/she is talking about; this start has troubled me for years since I got the game. You have to beat the princess slide in under 20 seconds; that's the other star on this board. No one would have ever guessed to do that with out using the internet.
