Hector the Reflector's Haunted House

Hector the Reflector's Haunted House is level 2-4 of 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 Ghost Piranha and the Invisighoul. The first section of the haunted house is a straightforward course through Boo Guys and Ghost Piranhas. For the next section, the players must enter an 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 Ghost Piranhas. 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 huge furnitureless Invisighoul.
