Prince Froggy's Fort

Prince Froggy's Fort is the fourth level in World 3 in Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3. It is the home of the boss, Prince Froggy.

Overview
Yellow Yoshi will start the level in a misty swamp, with a Egg Plant, allowing him to collect Eggs. Yoshi will have to jump from platform to another, while dealing with Shy Guys, Spear Guys, and Cheep-Cheeps in the water. He'll have to hit a ? Cloud, to cause a bridge to appear. This bridge will allow him to reach a tall plain with a Grinder, and Thorns, which Yoshi must hit to reveal a hidden Door. This door will lead Yoshi to a bonus area, where he can turn into Yoshi Submarine with the use of a Morph Bubble, and explore a vast lake, collecting Red Coins while dodging a spinning Mace. However, his time as submarine will be short, as he'll have to exit this area in the left. After the plain with the Grinder, Yoshi will find two Dizzy Dandys pretending to be Flowers, easily damaging the dinosaur if he's not careful. Right after this, Yoshi will find a door to the second area, which is a misty lake in a jungle, where Cheep-Cheeps jump out of the water in an attempt to harm Yoshi. He'll find a door here, which will lead him to another room in a jungle. Yoshi will find several Grinders and Short Fuses in this area, as well as Cheep-Cheeps. Yoshi will simply have to collect some Red Coins in a platform. However, he can also enter a door, which will lead him to a dark room with two Clawdaddys. If Yoshi defeats these two Clawdaddys, he'll gain a Flower. Since there's no other thing to do in this room, Yoshi must return to the previous area, where he must across an area with a spinning mace, and grey blocks that can be destroyed with eggs; there's a red coin here. Yoshi will also find a Spray Fish in the water, and a Flower near a spinning mace. He'll also find another door, leading to another watery room. This time, Yoshi must hit a Bucket with an egg, causing it to fall of the ceiling. Yoshi must then use it to across the water, while dealing with Cheep-Cheeps. He'll also find two red coins here. In the other side of the lake, Yoshi will find some Grinders hanging in the walls, and a ? Cloud containing a 1-UP. He must then return to the previous area, and use a Paddle Wheel to across the lake, but he must be careful, as there's Boo Guys in the ceiling throwing Bombs at him. He'll also find some red coins, and a ? Cloud containing a Flower in a platform. In the other side, Yoshi will find a Middle Ring and a door leading to a dark room. Here, Yoshi must across the dark corridors, while collecting red coins and defeating Clawdaddys. This is not a long room, however, as he'll find another door after the third corridor. This door will lead him to a room with Spikes in the floor, forcing him to hit ? Cloud in order to make platforms appear. There's also Lemon Drops in the ceiling. A flower above the spikes can be collected by hitting it with an egg. After this, Yoshi will have to use another Paddle Wheel to across a large area with Thorns in the floor, with the last flower in the middle of the route. After this, Yoshi must enter another door, which will lead him to a room with some Frog Pirates, a Dizzy Dandy, and the red door leading to the boss, Prince Froggy.
