Hector the Reflector

Hector the Reflector is the third boss of Yoshi's Island DS. He is a strange, egg-shaped ghost that resides in a Ghost House-like fort, filled with Possesed Furniture, Boos, and other supernatural creatures. His fight is unusual, taking into effect the full potential of each screean. When the fight begins, he is invisible on the top screen, but visible on the bottom. Yoshi can peek into the "mirror" botom screen, find Hector, then egg him on the top. After each hit, Hector throws a flowerpot at the bottom screen, "cracking" it. His Invisighoul minions also pick up furniture and fling it at Yoshi, but he can eat it for more eggs. After five hits, he vanishes, granting Yoshi access to the next level.
