Physical appearance
Despite being named after, Plessie is actually a big, bipedal. As such, it still features short but fully formed legs ending in feet with three toes, which allow it to run and even jump considerably high while running, and hands with three digits and a thumb, the latter being as wide as the arms and thus forming a fin-like structure when they are stretched, enabling it to swim with appreciable agility despite its size. Besides being three to four times as tall as Mario, even though the artwork made for the Super Mario 3D World Original Soundtrack shows it being around twice as tall as Mario, Plessie is visibly fat, and this trait is actually used to efficently slide on the belly outside bodies of water. Its body features a smooth skin which is orange on the upper side, while the bottom side, from the protrudring end of the snout to the tip of the tail and including the bottom part of the arms and of the hands, is white. The bottom of each foot, including the toes, is also fully covered by a white pad. Furthermore, the back features four darker stripes with rounded borders that are perpendicular with respect to the tail. Plessie's head features two big eyes, each with an orange eyelid, a white sclera and a big oval pupil surrounded by an aqua green iris. On the top and on the side, the eyes are surrounded by a black border followed by the brow ridge, which fully covers each eye. Right behind the eyes there is a twin-lobed crest resting on the median plane which is cyan colored, with the upper lobe being slightly bigger than the bottom one. The muzzle features protruding white cheeks on the back, and is relatively long and orange-colored on the top until the end, which is protrudring, extending beyond the lower jaw, rounded and fully white, featuring two crescent-shaped nostrils on the top. The mouth is toothless and features a wide, round, dark pink tongue. The tail is long and ends with a three-lobed structure resting on the coronal plane, similar to the crest and having the same cyan color as well. Plessie is always seen wearing a red bandana knotted on the left side of the neck.
