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)
