A deleted scene for the current version of "Hiccupire" was an ending scene where Poppy and Bridget get hiccups, and everyone tries to cure them.
One of the original ideas for "Hiccupire" was for Oxana to get vampire hiccups, and she would struggle to resist flying into the air when around human guests.
In this episode, Vampirina said that she wasn't afraid of anything. At the end of the episode, it's revealed that Vampirina is afraid of baby cows.
