On My Candy Love, there was an image of Jeanylotte's egg on the page for that site's event. If one hovered their mouse over it, Jeanylotte would pop out of the egg and tell the player that they could adopt them over on Eldarya.
Its appearance and ears may have been inspired by Digimon's Tokomon.
The oval shape of Jeanylotte as a baby seems to refer to an Easter egg.
It was mentioned by Mery in the line "You really are a Jeanylotte head!".
A costume released at the Easter 2022 Event is based on this companion and even given its own name: Jeanylotte's Fluff .
