Miss Petunia

Not to be confused with Petunia, a character in Paper Mario.

Miss Petunia, the Bathing Beauty (シャワーびじんミス・ブーニャ, Shawā Bijin Misu Būnya^?) is one of the Portrait Ghosts in Area Three in Luigi's Mansion. She can be found on the second floor of the mansion inside the bathroom shower. Luigi must suck up an Ice Elemental Ghost and shoot it at Petunia in order to make her vulnerable and expose her heart. Then, he can suck her up with the Poltergust 3000. Miss Petunia has 100 HP.

A book can be read in Nana's Room about Miss Petunia saying how Nana pulled a prank on her; this is an intentional hint for Luigi to shoot ice at Miss Petunia to defeat her.
