Azurill is the younger brother of Marill. Their mother is ill, so they do errands for her, such as the shopping, while also looking for a Water Float that they had lost. When the player picks up an apple that Azurill dropped, they experience their first Dimensional Scream. Azurill is later taken to Mt. Bristle by Drowzee and must be rescued by the player. The Water Float eventually turns up at the end of Amp Plains. Later Azurill falls into a nightmare and cannot be woken. The player must enter Azurill's dreams with the help of Drowzee to try to find out why. Azurill is woken by Cresselia once Darkrai has been revealed.

In Here Comes Team Charm!, it transformed into a Bellossom to tell Team Charm that trying to find the treasure was hopeless, then later into Sentret to convince them that they needed to get revenge on Team AWD. Once they reached the final chamber of Limestone Cavern, Ditto transformed into an empty treasure chest to cause Team Charm and Team AWD to fight each other so that neither would discover the Time Gear. Wigglytuff stopped the fight continuing after Team Charm knocked out Team AWD, and forced Ditto to reveal itself. Ditto apologized for its deception, revealing that it was actually Bellossom and Sentret, then showed them the Time Gear.

- Main article: Wigglytuff (Explorers of Time, Darkness, and Sky)
Guildmaster Wigglytuff before he evolved, and the main character of Igglybuff the Prodigy. He lived at home with his parents and often played with his friends Wooper, Smoochum, and Budew, but one day went on an exploration with the bullies Banette and Skorupi to the Murky Forest.
At the end of the forest, he met Armaldo, who usually would scare off any intruders. However, while Banette and Skorupi fled, Igglybuff was not afraid of him and Armaldo told him about exploring. Igglybuff then solved the puzzle of Armaldo's map in seconds, despite Armaldo working on its secret for a very long time. Igglybuff then convinced Armaldo to go on an exploration to the dungeon revealed by the map, Eastern Cave.
At the end of Eastern Cave, rather than solving the puzzle, Igglybuff chose to obliterate the door with his WOOM-TAH, impressing Armaldo. They found the treasure—a Defend Globe. Igglybuff wanted to go on more explorations because he enjoyed it so much, and eventually convinced Armaldo to make him his apprentice.
After exploring together for several months, the two decided to go to Fortune Ravine. At its end, Armaldo tried to solve the puzzle but ended up setting off the trap, dropping them into a Monster House. After emerging from the dungeon to find the ruins at its end, Magnezone, two Magnemite, Nidoking, Papa Wigglytuff, Mama Wigglytuff, Wooper, Smoochum, Budew, Banette, and Skorupi approached them. Nidoking told Igglybuff that Armaldo was actually an outlaw, and that they had to take him away. Igglybuff, upset, was about to WOOM-TAH the apprehending party, but Armaldo told him not to, or he would end up an outlaw as well. Armaldo gave him the Defend Globe, then was taken away by the police.
Lapras takes anyone with the Relic Fragment to the Hidden Land. Lapras was first seen by Wigglytuff many years ago, making him promise not to research the wall pattern. Many years later, Wigglytuff tells Lapras he cannot hold the promise any longer. After this, Lapras takes the team and Grovyle to the Hidden Land. Later, after Temporal Tower is saved, Lapras is asked about Palkia, but doesn't know much about it.
Mama and Papa Wigglytuff
Once Papa went mountain climbing with his son, Igglybuff, who would later grow up to be Guildmaster Wigglytuff. When they were climbing down the mountain, Papa Wigglytuff was almost crushed by a falling boulder, but Igglybuff used his WOOM-TAH to destroy it.
One day, Mama Wigglytuff gave Igglybuff some Gummis to share with his friends. Igglybuff ended up also using these Gummis to make friends with the bullies Banette and Skorupi, then went to the Murky Forest with them. Papa and Mama were pleased when Wigglytuff told them he had made a new friend—Armaldo—not realizing he was an outlaw. When Nidoking informed them that Igglybuff was travelling with an outlaw through Fortune Ravine, they accompanied Nidoking, Magnezone and the Magnemite to apprehend Armaldo and save Igglybuff.
Manaphy was first seen as an Egg, being found while the team was exploring a dungeon. He later hatches, wanting Blue Gummis, which must be provided. He is later taken by Walrein. Many days later, he comes back, wanting to join the team.
Marill is Azurill's sibling, having a minor role in the storyline. When Marill, Azurill, and Drowzee go to Mt. Bristle, Marill is left behind. Later, Marill and Azurill tell the team about the water float in Amp Plains.
Nidoking is an explorer who has been tracking down the outlaw Armaldo in the Special Episode Igglybuff the Prodigy. He spots them leaving a dungeon discussing going to Fortune Ravine. He then goes to tell Igglybuff's friends and family that he has been exploring with an outlaw.
