How to unlock all bonus videos

If I give an example it might be easier (but the example doesn’t exist maybe it does but ...)

Example: Having all the star pieces in the world 9-7 for example

I hope this will be understood for the next time I write about a video game

I remind you the game is called (New Super Mario Bros. Wii)

PS. I want clear answers not like the response from the first one who wrote to me

It must disappoint him that I say this but oh well that’s life

Goodbye
