Pokemon the Series: Ruby & Sapphire Season 602 Episode 10 Gone Corphishin'

There's a mysterious Pokemon on the beach, and it's burrowing through anything that's in its way--Ash and his friends, their tent, even Team Rocket! Our heroes try to get it out into the open, setting out Pokemon food and digging a pit trap to try to slow it down, but nothing seems to be working. Finally, Pikachu manages to hit the burrowing Pokemon with a Quick Attack, and a Corphish pops out of the sand, ready for battle! This Pokemon is strong, fast, and determined, and it turns out to be too much for Pikachu. But Ash and Treecko have been training hard since their defeat at the Dewford Gym, and with some help from his trusty Grass-type friend, Ash catches Corphish and has a new Pokemon for his rematch with Brawly!
