Phineas (パロンチーノ Paronchīno, Palloncino) is a sea lion who was first introduced in City Folk. He can be found in the city at between 9 A.M. and 7 P.M. in reasonable weather conditions (sunny or overcast/cloudy). He gives the player special hand-held items that the player cannot get anywhere else except wi-fi gameplay, for no purpose other than for joy and for free. He has been known to appear in a player's city for days in a row, or not at all for weeks.
In New Leaf, Phineas is now a scout master, and will appear in the player's town if they have fulfilled the criteria for one or more badges, which he will hand out when asked. Sometimes the player can talk to him again later and he will give another badge depending on the player's achievements. If the player has a pending medal to be received, he will always be present in the player's home town between around 9 A.M. to around 10 P.M, provided reasonable weather conditions as aforementioned.
