Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness/Chapter 17: The Guild's Crew

After the player tells the partner to go to the guild together, thats where they go. The partner stands above sentry post, and Diglett burrows to the top and says that its the player and partner, after such a long time, the whole guild comes out and welcomes them back in. The partner then shares with them what they witnessed in the future, but Chatot doesn't believe them, or Dugtrio, but Sunflora explans what she feels and that changes everyones minds. Wigglytuff says Chatot was believing them the whole time and Chatot, sort of stutteringly agrees. After they eat dinner, the team talks for a little and goes to sleep to discuss every thing in the morning. Wigglytuff and Chatot say to go to Torkoal the town elder, found at the Hot Spring. The team comes and Torkoal tells them that he knows and he tells them one thing but forgets the other. Torkoal said if he remembered he'd let them know. You'll have to travel with Chatot he is lv34 this dugeon is easy with lv34 and lv35 Pokémon at the end of dungeon Kabutops and two Omastar attack and Chatot shields you, battle and then you are done with the dungeon and meet Lapras.
