A Goofy Movie (1995)

Continuity mistake: At the end,when the car blows up, Goofy is blown out of his shoes and into the roof of the house. But as the movie fades out,he's got his shoes back on. How?

Bobby: Max, look, it's the Leaning Tower of Cheesa.

Trivia: Ariel from the Little mermaid can be seen after Max gets in trouble, she can be seen on the right when it cuts to his friends, she can be seen again when Goofy and Max go to the hotel pretending it is water - she can be seen as a light stand.

Question: I have looked all over the web for the wav of the sound Goofy makes whenever he is falling, which he does at least once in every cartoon he is in. It sounds like 'yah-ha-ha-hooey.' I have never found it, so can someone point me to where I might be able to download it?
