Hector the Reflector's Haunted House

Hector the Reflector's Haunted House is fourth level of World 2 in Yoshi's Island DS. It is also the third castle in the game. The level has a Haunted House theme, as implied by the title. It introduces three new enemies; the Boo Guy, the Polterpiranha and the Invisighoul.

Layout
The first section of the haunted house is a straightforward course through Boo Guys and Polterpiranhas. For the next section, the player must enter a Invisighoul-infested room to obtain a key, followed by riding an Arrow Wheel to a locked door. The door leads to an area with many Polterpiranhas. The final section is again infested with Invisighouls, but this time players must ascend a room as opposed to walking east. Next is the boss battle with Hector the Reflector, a large Invisighoul.
