Remember how I said Tara Strong used to be on Super Mario Bros? Well she isn't the only one. After a little research I found that Tabitha St. Germain also voice Kootie Pie, AKA Wendy O. on the same show.
I've got one more: Tracey Moore, who was the second voice of Princess Toadstool, was also the voice of the first Cheerilee, as well as the narrator and the mayor from Twinkle Wish Adventure. I mainly remember her because her voice reminds me a little of Megan from the 1980's My Little Pony series, even though Moore was never in that show. I did discover that she played Sailor Moon though, so now I have this mental image of Megan delivering Sailor Moon speeches.
On the other hand, Jeannie Elias, the first voice of Princess Toadstool,
did do some voices for G1 My Little Pony. Did we have a lot of turnover in cartoon voices in the early 1990's or something?
The MLP movie was originally gonna have a drunk Shipwreck seeing one of the ponies while drinking, before proceeding to smash his whiskey bottle and start praying to himself. So, yeah.
Now see, I read that, but then I went and saw the movie, and I still have no idea where in that film it would possibly make sense for Shipwreck to appear. Like Emidawg said, it could
almost work in a Big Brother Ponies episode...
