From Nookipedia, the Animal Crossing wiki
Pascal (ラコスケ, Rakosuke) is a special character that appears first in Animal Crossing: Wild World and later in Animal Crossing: City Folk and Animal Crossing: New Leaf. He is a red sea otter, with a yellow muzzle, black nose, and wide black eyes; he wears a beige beanie hat and dungarees, and has an unknown shell around his neck, probably a scallop. His name is a reference to a French philosopher, Blaise Pascal; it may also be a reference to the measurement Pascal, also named after the philosopher, which is used to measure pressure underwater. It could also be derived from the word "scallop". In Animal Crossing: Wild World and Animal Crossing: City Folk he appears in the player's town on random weekdays from 6 A.M. to 12 A.M. and is easily noticed by the villagers.
Pascal is known for his philosophical tendencies, making him well known amongst the villagers in the player's town. Most of his philosophy is marine-themed. Every time the player talks to Pascal, he jumps into a river floating downstream until out of sight.
In Wild World, he appears during random weekdays by the river mouth from 6 A.M. to 12 A.M., where the player can listen to one of his diffuse and sometimes random thoughts. If a player decides to, Pascal will give him or her a piece of ship-themed furniture before performing a perfect dive into the sea and swimming off.
Pascal is a key member in the Wild World Golden axe trading event. In exchange for a scallop, which is obtained from Tortimer for a massage chair, Pascal will give players a golden axe or a photo of himself.
His picture quote is "The more you learn, man, the less you know.", and he is one of seven special characters in Wild World who gives their picture out, the others being Tom Nook, K.K. Slider, Pelly, Phyllis, and Katie and Kaitlin.
Sometimes cranky villagers will state that when Pascal was little he got hit in the head with a soccer ball, and from then on, he started saying random philosophy. It is not known if this rumor is true.
In City Folk, Pascal stands on one of the town's bridges on random weekdays from 6 A.M. to 12 A.M.. Though Booker will not tell players when he is in their town, the villagers will usually know. After sharing some philosophy, Pascal does a triple flip into the river, floating toward the sea, scaring any fish along the way. If the player is carrying a scallop when talking to Pascal, he will exchange it for a piece of ship-themed furniture.
In Animal Crossing: The Movie
Pascal can be encountered when the player goes diving. If the player catches a scallop, Pascal will appear and ask to have it. When Pascal is given a scallop, he gives the player a piece of pirate furniture in return. He appears once per day and is absent on special days.
Pascal appears as a spectator in the Smashville stage, and as a trophy.
Pascal once again appears as a spectator in the Smashville and Town and City stages, and as a trophy.
