Game Play Walkthrough Video
Green Star 1
Toss a bomb under the blocks below the green star. You will then use the raised blocks as steps to reach the first green star.
Green Star 2
Use the bomb from the previous tank to blow up the rock on the right side. You will then obtain the next green star.
It’s easy to miss this one. Use a bomb from the previous tank to blow up the Rock Block and free the Green Star. Beware the Fire Bro.
Green Star 3
You’ll see this Star near the end of the course. Use the ground pound or the tail attack to make a bridge out of blocks.
Grab another bomb after getting the third green star. Toss the bomb at the cracked bowser picture at the end of the stage.
Boom Boom comes back again, now he attacks faster and the shell splits from his attack. Do the same thing and jump on him three times to take him out.
