SpongeBob's Boldore

SpongeBob's Boldore is the eighth Pokémon that SpongeBob obtained in the Andy region.

As a Roggenrola
Boldore was introduced as a Roggenrola in Gotta Catch! when it literally crashed into Ken's food in distress. Ash battled it, but it managed to knock out both Oshawott and Tepig. It later met Ash again when they came to investigate a tunnel, where they found Team Rocket harvesting wild Roggenrola for their cannon. It too was collected, and Ash managed to save it, but not before Team Rocket caused a cave in with a powerful Flash Cannon created by all the Roggenrola they collected. After they escaped the tunnel, they found Team Rocket in a warehouse where SpongeBob and Roggenrola managed to free the other Roggenrola. Once they were reunited, they sent Team Rocket blasting off with a combined Flash Cannon. After being cured at the Pokémon Center, Roggenrola challenged SpongeBob to a rematch, where it was eventually defeated by Tepig and captured.

Boldore
Roggenrola was used in SpongeBob's Gym Battle against Woody in Battling for Roundup Gang where it was sent out to counter his Excadrill with its defenses. After Roggenrola's Sandstorm attack fails, it was hit by several Drill Run attacks and finally a Horn Drill. However, Roggenrola's Sturdy allowed it to survive the attack. Afterwards Roggenrola evolved into Boldore, survived another Horn Drill using Sturdy and ended up head to head with Excadrill. Using the red stones on its back, Boldore was able to communicate its new power to Ash and used a new move: Rock Blast. After pushing Excadrill back Boldore revealed to its Trainer that it could use Rock Smash and clashed with Excadrill's same move. Eventually Boldore was able to overcome Excadrill and won SpongeBob the Cowgirl Badge.
