Jadeybug is very nice and polite, but absent-minded and clumsy. She has difficulty to remember where the stampers are, since she puts them in various places, even inside her lunchbox or on top of her mailman's hat. She comforts Strawberry in "Strawberry's House Pest" about how her cousins have been kicked out of every place they've ever stayed and that she was the first to not kick them out, they've always been that way. She has so many stamps to keep track of, she accidentally stamps a package to be delivered to a different town with too many stamps which are also the wrong stamps until she finds the correct one.
Jadeybug's skin is colored with pale and dark purple stripes. She has dark purple hair-like markings framing her head resembling a single curled bang and side parts. Her face is light pink in color. She has blue eyes, red lips and a mole on her upper lip. She has curled antennae and two pairs of wings: the bottom wings are transparent blue, and the top wings are red with blue spots. She wears large earrings, a green scarf and red shoes. During work hours, she wears white cuffs and a mailman's hat with a strawberry sticker. On social events, she wears bracelets and high-heeled red shoes.
