From Bulbapedia, the community-driven Pokémon encyclopedia.
Island of Fossil (Japanese: 化石のしま) is one of the eight sets found in Pokémon Card GB2: Here Comes Team GR! for the Game Boy Color.
The booster pack image features an Omanyte.
Club Masters and their Club Members usually give out these booster packs when they are defeated.
Island of Fossil includes cards from Base Set, the Jungle expansion, and Fossil expansion. It also includes a number of cards from the Japanese-exclusive Expansion Sheets and Intro Pack. Electrode is included as a then in-game exclusive card.
