After all of that time trying to figure out what happened with "Fuli Speeds Ahead", it turns out, the episode was simply renamed. It continues my suspicion that Disney is convinced that boys don't like Fuli, as not only did they rename the episode, they didn't even bother showing her in the preview. Bunga's part of the plot was important, and one could argue it was the real "A" plot because the episode ended on it, but Fuli's plot shouldn't have been brushed under the rug like it was.
Have a super fatigued Fuli image to celebrate the end of this mystery.
