In Super Mario World, World 4 at the Star Road course, I'm unable to get to the key.
Here's an image of what I want it to look like, in fact the boxes are just empty dashed frames, but can't stand on them.

You have to break (touch) the rope at the level's exit to earn stars. The higher it is when you break it, the more stars you get — up to 50. Getting all 50 gets you three bonus extra lives.
The white horizontal bar between the two vertical striped bars is the 'rope' to which I refer.
Once you have acquired 100 red stars, you enter a bonus game where you can earn extra lives.
The minigame starts with 8 squares that had changing icons on them (the one in center does not change). The 8 squares around the center rotate around the middle square. The objective is to hit the moving squares to make them stop changing their icons. Once you are done, you get an extra life for every row of similar icons.
There is a secret warp in the Star Road. Upon entering it, you will end up in the Special World. If you complete all 8 of the Special World levels, a new Star Road appears with a warp that leads back to Yoshi's House. If you enter it, some drastic changes occur in Dinosaur Land:
- World backgrounds change (to a Fall-like instead of a Spring-like colour scheme).
- Koopas transform into Mask Koopas.
- Piranha Plants will change into Pumpkin Plants.
- Jumping Piranha Plants will turn into Jumping Pumpkin Plants.
- Bullet Bills are replaced with Pidgits.
- Goombas turn into a yellowish color and have sunglasses. (GBA version only)
- Pokeys turn into sawblade-like creatures. (GBA version only)

These changes occur in the entire world, and are permanent.
