Allergia Gardens

Allergia Gardens is the final level in Wario: Master of Disguise. Wario comes here in order to search for the fifth and final Wishstone fragment. The level takes place in a vast, labyrinthine garden at sunset with many vines, spikes, and mushrooms.

Many areas require the player to solve mushroom-based puzzles in order to continue. The blue doors with looping arrows on them will simply take Wario back to the same room; the green mushrooms in the area must all be pressed in order to turn the blue doors green and let Wario continue. Some of the mushrooms are invisible and require Genius Wario to see them and press them down. If a blue mushroom is pressed, either by Wario or by an enemy, the green mushrooms will be pushed back up and the player will have to start over, but once all of the green mushrooms in a given area are pressed, they will remain pressed and cannot be pushed back up. There are also red mushrooms that when pressed, cause vines that normally impede Wario's progress to wither.

The level also features devices with huge gears in them, each with two switches on them. Pressing the switches in a certain order will cause a ladder to appear. The correct order for each switch is indicated by arrows displayed somewhere in the level. However, one of the arrow sets is invisible and requires Genius Wario to see it, and another set of arrows corresponds to a room with two switches, meaning the player must remember not only the directions of the arrows, but the colors as well.

Episode 10: The Final Face-Off!
Continuing from where the previous episode left off, Carpaccio leaves in search of the final Wishstone piece. Count Cannoli leads Wario to Allergia Gardens, then tells him that he's done playing tricks on him and that Carpaccio came here to protect the last piece of the Wishstone.

When Wario catches up to Carpaccio, he takes the Crimson Diamond off of the door leading to where the final tablet is. Carpaccio then disappears and the color of a nearby door as well as the symbol on it changes. Goodstyle notes that the color of the door has changed and suspects that the garden is full of surprises. In order to change the blue doors back to green, Wario must hit all the green mushrooms in the area.

Wario eventually finds the Crimson Diamond and opens the big door. Carpaccio tries to stop him from reassembling the Wishstone, but Wario ignores him. The Wishstone reforms, and Tiaramisu emerges from it. She reveals that her true name is not Tiaramisu, but Terrormisu, and that she is an ancient demon who had been sealed inside the Wishstone.

Goodstyle now tells Wario the full story of the Wishstone. Poobah the Pharaoh had called upon Terrormisu to grant him a wish, but she demanded that he starve his people in exchange for it. The pharaoh agreed, but Terrormisu did not uphold her end of the bargain and instead stole everything from him, turned his palace into a pyramid, and sunk it beneath the desert sand. However, a mysterious stranger showed up and sealed Terrormisu away inside the Wishstone, then split it into five pieces.

Terrormisu reveals that Sweatmore Peak is a nexus of dark power, which is how she was able to reach out to him and manipulate him despite being sealed inside the Wishstone. She prepares an attack, but Cannoli arrives just in time to save Carpaccio. He carries him off to safety while Wario fights Terrormisu. Once Wario defeats her, she gives up and flees to her home dimension.

At this point, Goodstyle reveals his true form and identity. He is actually the first member of the Cannoli clan and the one who sealed Terrormisu away inside the Wishstone. He assumed his wand form in order to look for a master who could use his power to defeat Terrormisu once and for all, which is why he led Wario on his hunt for the Wishstone pieces. In exchange for defeating Terrormisu, Goodstyle gives Wario all of the treasure the Cannoli clan had accumulated.

Wario gloats about his newfound riches, but upon returning to the real world, he realizes that he is unable to take the treasure back with him.

Special Episode Part 5
Terrormisu returns to Allergia Gardens because she left some of her possessions behind, and offers the "most beautiful gem from her dimension" to whoever can find them for her. Wario gives her the stuff, expecting an actual gem, but Terrormisu tells him that by "most beautiful gem from her dimension", she was talking about herself. She wants him to go back to her world with her so that they can conquer it together. Wario promptly leaves, with Terrormisu following behind.
