Emily was always “Emily” officially until we saw the video for the Bowling For Soup song “Emily” (from whence we derived her name), which features a girl wearing a T-shirt that reads “Emily the Jaret-Slayer.” Ours became “Emily the Carrot-slayer,” then officially.
Unofficially, she’s “Nibbler,” “Hopper,” “Big Nibbler,” “Big Hopper,” “Bunny Girl,” “Nüny Ears,” or “Fluff-Tail.”
Peekaboo is just “Peekaboo” officially, although she sometimes goes by “Baby Bunny,” “Baby Nibbler,” “Baby Nüny Ears,” or “Gobbler.”
Tobermory becomes Toby or Kitty Baby.
Guy Incognito-- our parrot Murphy also goes by “lil chicken” and sometimes “roast squab.” My husband calls him “beaky buddy” and the in-laws “beaky-boy.”
