Wigglytuff was considered a prodigy in exploring even at a young age when he was an Igglybuff. Much like his older self, he is very carefree and naive to the point of befriending the local bullies Gligar and Banette.
One day when the bullies challenged him and his friends Smoochum, Wooper, and Budew in exploring Murky Forest, he was the only one who didn't back away. The three explored Murky Forest until they came across a cave where the locals believed that a monster inhabited there. As the 'monster' approached, only Igglybuff stood his ground and even tried befriending the monster which turned out to be an Armaldo. Armaldo at first was suspicious and somewhat annoyed with Igglybuff's antics, but later he revealed himself to be an explorer, which piqued Igglybuff's interest. Armaldo then showed him a treasure map which he was unable to decipher. When Igglybuff got a hold of the map, he ignited it on a nearby campfire, much to Armaldo's shock. However, Igglybuff revealed that he did so because he noticed that there were two layers in the map and the only way to make the map readable was by burning it. The map reveals that the treasure was located in Eastern Cave; Igglybuff became excited and was eager to join Armaldo in obtaining the treasure. Armaldo was reluctant at first, not wanting to leave his home, but eventually gave in.
The next day, Igglybuff visited Armaldo again and the two of them paired up to venture to Eastern Cave. As they reached the end of the cave, they came across a treasure chest that contained a Defend Globe, said to boost Template:Type2. Igglybuff was excited at their first success, and began to call Armaldo his master.
The two then went on many adventures, one one of the adventures however, both of them were spotted by a Nidoking. Back in town, Igglybuffs friends noted on his disappearances and told his parents. The bullies claim that he's been disappearing into Murky Forest a lot lately much to the shock of everyone around him.
The two secretly went on many adventures after that, but Igglybuff's friends began to take notice of his disappearances, and notified his parents. The bullies claimed that he was disappearing to Murky Forest frequently, much to the shock of everybody. Igglybuff and Armaldo, furthermore, were spotted on one of their adventures by a Nidoking.
Eventually, Igglybuff and Armaldo came across and explored Fortune Ravine. However, Igglybuff's friends and family, along with the aforementioned Nidoking, apprehended the two. Armaldo was revealed to be a B-Rank Outlaw, and gave into the arrest. Igglybuff, however, refused to believe that Armaldo was a criminal, and almost burst into a rage if not for Armaldo calming him down. He thanked Igglybuff for the happy times and believed that he would become a great explorer. As a parting gift, Armaldo gave him the Defend Globe from their first exploration, which Igglybuff, now a Wigglytuff, carries and treasures to this day.
Personality
Wigglytuff acts very easygoing and somewhat naive, which leads those such as Team Skull to underestimate him, but is known for his explosive temper. Despite his childish behavior, Wigglytuff is an accomplished explorer and helps the team discover the mystery behind the Relic Fragment and the Hidden Land. He is also extremely powerful, proving able to withstand Team Skull's "Noxious Gas Combo", which has easily knocked out the player's team several times, as well as defeat Team Skull singlehandedly. Wigglytuff also became serious when the Guild was asked to help capture Grovyle.
After the credits roll, he appears under the guise of "the grand master of all things bad", a "foe" with his "minions" (the rest of the Guild members) that the player must overcome in order to claim the treasure from Luminous Spring and graduate from the Guild.
Wigglytuff has an obsession with Perfect Apples, and is known for crying out loud if he does not get one every day, as feared by the other Guild members. This obsession is taken further with a Perfect Apple being placed as a "treasure" for the player's graduation exam. Wigglytuff is also good friends with Chatot, having explored many places such as Brine Cave together.
