Super Mario World - 100% Walkthrough, Part 19: Vanilla Fortress & Butter Bridge 1

The first fortress is not only part of a secret path, but it's also under water. It's a little tricky, but nothing compared to the later ones. Butter Bridge 1 is much easier, and it's not as annoying as the other forced pace level. Managed a minor fail in the end when I was going for another life combo.
