Tentacruel is Pokédex #073, generation 1 (Kanto). Tentacruel is a Stage 1 Water Pokémon with 70 HP. The card says it evolves from Tentacool. In this catalog that name is Tentacool (#072).
Tentacruel sits at 38/147 in Aquapolis, position 38 of 182. Before it is 37 Suicune, and after it is 39 Togetic. The set belongs to the E-Card series. It was released on January 15, 2003. The printed size is 147. This checklist is longer, at 182 cards. The listed rarity is Rare.
Strange Tentacles is listed as Poké-Power. Once during your turn (before your attack), as long as the number of Energy cards attached to the Defending Pokémon is less than the number of Energy cards attached to your Active Pokémon, you may choose an Energy card, if any, in your opponent's discard pile and attach it to the Defending Pokémon. This power can't be used if Tentacruel is affected by a Special Condition. The attack Poison Sting lists 20 damage. The cost is Water, Colorless. Flip a coin. If heads, the Defending Pokémon is now Poisoned. Weakness is Lightning ×2.
Tentacruel (#073) has 15 other cards in the catalog. Those other cards are in 15 sets. The other printings with a release date run from 1999 to 2023. The earliest other card is Tentacruel 44/62 in Fossil (1999). That card lists 60 HP, and this one lists 70 HP. The rarity there is Uncommon, and here it is Rare. Kagemaru Himeno illustrated that card, and Hajime Kusajima illustrated this one. 11 other cards of Tentacruel list a different HP.
The illustrator line reads Hajime Kusajima. I count 206 other cards in the catalog with that illustrator.
Aquapolis set binder is where a full Aquapolis set goes. This card fills one slot there. A generation binder holds one card of each species. Tentacruel can fill a slot in Generation 1 binder (Kanto). I still need this card.
