World Flower-1: Switch Shock Circus

Right at the start, don't rush forward! Instead, turn around and hop into the Mystery Box you see behind you. Inside, you'll find some Mushroom Trampolines. Your goal is to use these to reach the Switch Panels above. Now, while you *can* jump on the trampolines, it's way easier to just use the cursor on your screen (or the touchscreen if you're playing on a handheld) to activate the panels directly. This is how you'll grab the first Green Star.

After that, head up the steps. You'll encounter a bunch of Switch Panels and some annoying Fizzlits. Take your time here! You can actually use that same trick from the Mystery Box to activate the panels from a distance, making it much simpler to get past them. Keep activating panels until you can progress.

In the next area, look to the left. There's a ?-Block there. Hit it to get a Lucky Bell power-up. This is super helpful for dealing with the Fizzlits that are hanging around. Once you've cleared them out, you can activate the Green Star Ring.

With the enemies dealt with, you'll have a clear path to collect all the Green Coins scattered around, which will net you the second Green Star.

Now, head into the next area. You'll see more Switch Panels, more Fizzlits, and two Hammer Bros. My advice? Take out all the enemies first. Seriously, it makes dealing with the Switch Panels so much less stressful when you're not dodging attacks. Once the coast is clear, you can focus on activating all the panels.

Next, you'll find a clear pipe that acts as a cannon. Take it to the final area. As soon as you arrive, look to the right and break the wooden boxes. Inside, you'll find a baseball. You'll notice two blocks sticking out from the main platform. Carefully jump onto those blocks, then toss the baseball towards the right. If you aim it right, you'll grab the third Green Star!

Finally, hit the Switch Panels in this area to lower a ledge, which will give you access to the very top of the Goal Pole.
