PheNOMNOMenons cart ladies

The PheNOMNOMenons cart ladies are two Earth pony sisters who appear in the IDW comics'.

Development and designs
They were created for Friends Forever Issue 12 by writer Barbara Randall Kesel, with the script description "The two sisters running the cart are plush avatars of pony happiness: they resemble the treats" "in their shiny colorful way.They [sic] have their manes done up in rounded buns with shiny hairnets." "Their hooves are bedazzled to match their ‘noms. They appear friendly, prosperous, and well-fed." They were designed by artist Brenda Hickey, who took design inspiration from Japanese Sweet Lolita fashion, was asked "Are they from the Lollipop-Guild  [sic]?" and replied "That is likely what their origin story is!", and later stated that "they're not a reference." They were color-designed by colorist Heather Breckel.

Neither their names nor their cutie marks are revealed in the issue, but Brenda Hickey produced artwork showing their cutie marks and named them Fawn Doo (a pun on fondue) and Marcie Pan (a pun on marzipan) —names approved of by Barbara Randall Kesel. Brenda Hickey later produced artwork depicting 'Marcie Pan' as a human.

Barbara Randall Kesel has been asked "is the duo donning the air of eerie mischief IRL, or does it belong with Pac-Mare & the board game? :)" "I mean, when they start looking sort of sinister, tempting Pinkie to keep eating their treats, is it real or her imagination?" and answered "Well, y'know, when the treats call and you try to resist, doesn't EVERYTHING look sinister?"
