Cuddles, Giggles, Mime, Petunia, Pop, and Lumpy are all featured on the safety sheet Flaky looks at. Seeing as how they're all currently on the plane, alive and well, it would have made more sense to use Generic Tree Friends on the sheet. However, the people making the show could have been trying to save money this way by recycling the same character models again instead of creating new ones, seeing as how the TV series got cancelled because of budget problems.It could also have been foreshadowing for later in the episode.
After Mime's head is run over, one of Mime's eyes can be seen blinking.

The zoom in when Flaky first looks at the plane references numerous Alfred Hitchcock movies.
The way Flaky gets scared while she's in the plane may be a reference from Final Destination 5, where the character, Sam Lawton, worries about dying in an airplane with Molly Harper. It may also be a reference to Final Destination 1. Alternatively, it may simply be another of Flaky's many phobias.
