Dwebble was first seen when Ash and company were on their journey towards Nacrene City in A Home for Dwebble!. Dwebble was busy making its house out of a rock, but three more Dwebble appeared, attacked it and stole its rock, before escaping. Dwebble tries to chase after them but fails. Ash and the others witness this, they try and help Dwebble, but it is scared of the trio and attempts to run off. Pikachu tries to assure it, but the Rock Inn Pokémon attacks Pikachu with Slash. Pikachu dodges its attack and Dwebble strikes a rock instead. A piece of the rock flies off and hits Pansage on the head. Dwebble feels bad and apologizes to it. The gang tries to help it but Dwebble does not want any help and runs off.
Dwebble without its rock
It later returns to the group and Cilan invites it to have dinner with them. During dinner, Pansage collapses from a fever to which Ash suspects was caused by the rock that hit it earlier. Dwebble becomes overwhelmed with guilt. It later watches over Pansage as it sleeps and soon falls asleep right beside it. The next day, after Pansage recovers, Dwebble decides to search for its rock. With the help of the gang, it defeats the other three Dwebble and gets its rock back. Later, after the group says their goodbyes and start to walk away, Dwebble starts to follow them wanting to be a part of Cilan's team. Cilan agrees and captures it.
In BW031, Dwebble fashioned a giant scalchop out of stone for Ash's Oshawott to use in place of the one he lost.
Personality
Dwebble can be described as a little Pokémon with a lot of heart. When its rock that it had worked hard on was stolen from it, it stopped at nothing to try and get it back, despite being outmatched and overpowered. Because of the dedication it took to make its home, it refused to make a second one. It has also been shown to be fearful of humans at first. Dwebble is also a very caring Pokémon as seen when it stayed up to watch after Pansage. On top of all that Dwebble is smart and resorceful, using great tactics to win back its home.
