25. Harry's arrival coincides with a meeting of the Order, a meeting conducted behind closed doors so that none of the children can listen in. Fred and George provide an extendable ear for better listening. What happens to the ear?
From Quiz "The Order of the Phoenix" Part 1
Answer:
Crookshanks gets it.
The ear works splendidly, with Harry, Ron, Hermione, Ginny, Fred and George able to hear what is being said in the meeting. Then Crookshanks, Hermione's cat, starts to play with the ear, which is dangling from a long string in the most enticing fashion (from a cat's perspective). The cat manages to separate the ear from the string and takes off with it. A later shot of the cat licking its lips and seeming to burp, leads one to believe that the ear was eaten.
