Bigger Boo's Fort

Bigger Boo's Fort is the fortress level of World 2 in the game Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3.

Overview
The player starts off in a room with a Boo and an Exclamation Mark Switch on their right, which needs to be activated so a lava pit can be crossed. At the end of this segment is a door which leads to the next room.

In the next area is a Winged Cloud and another door, if the door is entered, the player will need to defeat to Big Boos which will cause a Flower to appear. If the Winged Cloud is hit with an Egg it will cause a bridge to appear, cutting off the middle section of the room, that will lead to the top of the room, where there are several Gusties, which leads to a small platform with an Exclamation Mark Switch on it, this needs to hit so a path to a Winged Cloud containing a Key will appear. The Key can be used to open a door at the start of the room. In this room are several Boos and Big Boos, as well as some Red Coins and a Flower, at the end of the room is a Warp Pipe that leads to a small platform in the room before it. On this platform is a Crate that contains some Stars. Due to going into a different room, the player can now use a Flatbed Ferry and get to the middle section of the room, that had previously been cut off by the stairs, and get to the Middle Ring as well as the path to the next area.

In the next area, are some rising stones and Firebars, after this small segment is a Post which is then ridden across lava to a Warp Pipe that goes to the next area.

In the next room, are several Boos, Big Boos, Eggs and the door to the next area. Near the end of this room is a destructible ceiling part that leads to a secret area. In this secret area are several Boo Balloons, a Boo Man Bluff, a Warp Pipe that spawns Boo Guys and a Flower.
