This trailer was taken from the Wii version of the new Super Mario Brothers, not don’t you wish you could complete levels as easy as this? Well I can make it a little easier for anyone who already owns the game and they would like 99 lives to help them get through it.
When you are in world 2-3, keep an eye out for the two Piranha Plants somewhere just after the mid-level point. You will see a staircase and a turtle will be descending down the steps. Counting from the bottom up wait until the turtle is about to leave the third step and then jump on it.
Perform this correctly and Mario will continue to pounce up and down on the turtle earning you 99 lives!! Don’t worry if you miss the turtle, just turn around and walk back left before returning as it will respawn. In the original version of Super mario Brothers this same trick would give you unlimited life.
Now assuming you are mini Mario lets us assume you have lost a few lives before reaching world 7-4. Pass through this stage ensuring you stay on the left hand side. Eventually you should see a question mark appear (?) on a box next to a ledge. Jump onto this box then immediately onto the ledge. Now making sure you stay tight up against the wall jump off the ledge and you will reach another platform which has a red flagpole. This unlocks a Mushroom house North of world 7-4 unlocking a 1-up. You can now continue unlocking 1-ups until you reach a total of 99.
