In water, Mudkip breathes using the gills on its cheeks. If it is faced with a tight situation in battle, this Pokémon will unleash its amazing power - it can crush rocks bigger than itself.
This card was included in the English EX Ruby & Sapphire expansion, first released in the Japanese Mudkip Constructed Starter Deck, with artwork by Ken Sugimori. The Holofoil version found in the Mudkip Constructed Starter Deck was printed in English as one of the Nintendo Black Star Promos and awarded through various European POP tournaments in July 2003. It was later reprinted as another Nintendo Black Star Promo with different artwork by Atsuko Nishida and was awarded through the Pokémon League in November 2003. The Japanese version was released as part of a McDonald's campaign in January 2003. The print released through POP tournaments in Europe has a foil Poké Ball symbol in the bottom right of the illustration.
