World 1-A: Chargin' Chuck Blockade (1 Star, 0 Stamps)

If you don't want to get the Yellow Star, you can also attack them using a powerup. The best way to get rid of them is to get on the platform to the left and hit the ? Block to get a Yellow Star. Star 3: Just to the right of where you'll find the stamp, there is a stack of Goombas with a Green Star in the middle of them. Jump into the clear pipe on the wall and it will take you to a hidden room with the Stamp. Now get on it and jump again to reveal a second hidden block. Stamp: When you come to the area with a long question Mark Box and two clear pipes on either side, jump on top of the block to the right to reveal a hidden block. Defeat the two Koopas within 10 seconds to win this Star. Star 2: Shortly after you've hit the checkpoint flag, jump up the purple blocks and enter the Mystery Box. Jump between the two to snatch a Green Star. Star 1: Make your way right through the cave until you come to an area where a set of cloud platforms is going up and another set right next to it is going down. World 1-2: Koopa Troopa Cave (3 Stars, 1 Stamp)

When you see the giant Brick Blocks, do a ground pound to break them up. Now that you're huge, quickly drop back down to the bottom level and continue right across the bridge. Run up the tree next to the Stamp pipe and you'll see a large bunny at the top of the cliff. Star 3: You'll need a Mega Mushroom to get this one. Stamp: Just after the pond with the rabbit, there's a pipe in a cliff.
