I'll give it a try.
The attraction is 20,000 Leagues Under the Sea.
2. Mr. Toad and 20,000 Leagues have a grudge against Winnie the Pooh because Pooh took over the place formerly occupied by Mr. Toad, and Pooh's Playful Spot set up camp on territory once occupied by 20,000 Leagues.
3. People might think that Alexander Gould provided a voice in this attraction because the journey was narrated by Nemo. But Gould lent his voice to Nemo the clown fish. The Nemo who narrated the undersea journey was Capt. Nemo, voiced by James Mason.
How'd I do?
(In the event that this is correct, I will "pass" the honor of the next puzzle to whoever wants it as I will have to close up shop soon and won't be able to monitor answers.)
