Green Star #1
A Fire Bro. will throw fireballs into two clear pipes connected by a passage with the Green Star inside. Either avoid the fireballs and go for the Green Star, or get ot the other side and take out the Fire Bro. first. If you have a Fire Flower in hand, throw a fireball right at the Fire Bro. to take it out.
Green Star #2
When you got to the Thwomp, jump on top and have it take you to the platform above. Run to the left and enter the green pipe. Use the flip panels inside to guide the green ball to the P switch.
Green Star #3
Before you hop through the Green Star Ring, take out the Blocksteppers with the nearby POW blocks. This will allow you to collect the eight Green Coins with ease.
Stamp Location
Right before the Goomba Tower is a Firebar with a Question Block. Ground pound the block to have it rise in the air, taking you right to the Stamp.
