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 starts the level in a misty swamp, with a Egg Plant, allowing him to collect Eggs. Yoshi has to jump from platform to another, while dealing with Shy Guys, Spear Guys, and Cheep-Cheeps in the water. He has to hit a Winged Cloud, to cause a bridge to appear. This bridge allows him to reach a tall plain with an Ukiki and Thorns, which Yoshi must hit to reveal a hidden door. This door leads Yoshi to a bonus area, where he can turn into the 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 a submarine is short as he has to exit this area to the left. After the plain with the Ukiki, Yoshi finds two Dizzy Dandys pretending to be Flowers, easily damaging the dinosaur if he is not careful. Right after this, Yoshi finds 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 finds a door here, which leads him to another room in a jungle. Yoshi finds several Ukikis and Short Fuses in this area, as well as Cheep-Cheeps. Yoshi simply has to collect some Red Coins in a platform. However, he can also enter a door, which leads him to a dark room with two Clawdaddys. If Yoshi defeats these two Clawdaddys, he gains 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 also finds a Spray Fish in the water, and a Flower near a spinning mace. He also finds another door, leading to another watery room. This time, Yoshi must hit a Bucket with an egg, causing it to fall off the ceiling. Yoshi must then use it to across the water while dealing with Cheep-Cheeps. He also finds two red coins here. In the other side of the lake, Yoshi finds some Ukikis hanging on the walls and a Winged 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 also finds some red coins, and a Winged Cloud containing a Flower on a platform. In the other side, Yoshi finds 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 finds another door after the third corridor. This door leads him to a room with Spikes on the floor, forcing him to hit a Winged 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 has to use another Paddle Wheel to across a large area with Thorns on the floor, with the last flower in the middle of the route. After this, Yoshi must enter another door, which leads him to a room with some Frog Pirates, a Dizzy Dandy, and the red door leading to the boss, Prince Froggy.
