Character mistake: Misty is notoriously afraid of bugs. She makes this clear whenever bugs are around. She seems to be OK with Tracey's Venonat, but for some reason doesn't think it should be classified as a bug, when its type is Bug/Poison, and it's quite obvious that "Venonat" comes from "venom gnat, " a gnat being an insect. She even directly states that "At least they're [Venonat and Marill] not Bug types." [This error doesn't happen in the Japanese version.]. (00:03:19)
