This card was included in the Base Set with artwork by Ken Sugimori, first released in the Japanese Expansion Pack. It was included in the Trainer Deck B with an exclusive red border and "Trainer Deck B" printed on the back of the card, distributed to prototype Pokémon Leagues before the TCG officially launched in North America. In Japan, this card was released as an Unnumbered Promotional card with different artwork by the same artist. It was first available through the Trade Please campaign that ran from February 10 to July 31 in 1998. Participants were required to mail a flyer included with copies of Trade Please by Suzukisan to MediaFactory along with any two Pokémon trading cards and a return envelope within the campaign period. Participants could select a "course" detailed on the flyer by writing in the appropriate space. The "A Course" included a Charizard card and a Trade Please! promotional card. The "B Course" included a copy of this card and the Trade Please! card. The "C Course" included a Venusaur card and the Trade Please! card. MediaFactory would then send the two cards from the chosen course to the participant, completing the trade. This print was later reprinted in the Intro Pack and again as part of the Pokémon Song Best Collection CD. The original Base Set print was later reprinted in the Base Set 2 expansion.

The Unnumbered Promotional prints available through the Trade Please campaign and in the Pokémon Song Best Collection CD have the Pikachu Records logo in place of an expansion symbol.
A few copies of the card lack the word "Stage" in the text in the upper right explaining how to play the card.
A few copies of the card have a red ink dot above Hydro Pump's Energy Cost.
