Jump on him. Jump on him.
To get to World 4 in super Mario bros all you have to do is defeat the World 2 boss with mini Mario. Oh and by the way its world 4. 1 ground pound acts as a jump.
kill the boss
You have to have (or be in) mini Mario form and kill the boss in world 5.
hit him 6 times to kill him by chaz99
If you beat the boss in super mini form, instead of running to the next world, you'll fall into a tiny crevice that will lead you to world four.
well, first you need a mini mushroom. head back to world 1 level 4 to get one. then go to the final boss level in world 5, eat the mini mushroom, and kill the boss. it'll take you from there.
get the right pattern of floors to defeat the boss kill baby bowser, jump behind bowser and dash to the switch then jump on it
In world two's final castle you have to beat the boss as Mini Mario. You have to ground pound on him three times and he will be dead. You get to world six by just just beating world five's boss.
jump on it
If you have flower power it takes between 9 and 13 shots to kill however if you are super Mario you must jump on its head 3 times but if you are normal Mario or mini Mario you must do 3 ground pounds on its head to kill it.If you are mega Mario you just step on it and it dies.
(The hey is wrong with you?) No, you cannot kill Luigi in Super Mario galaxy. (He's too precious)
What I did was be my normal self and kill the baddie 2 times and then turn into a small perosn on the last hit.
