The Defending Pokémon can't retreat during your opponent's next turn.

Diamond & Pearl is a set in the Diamond & Pearl series. It was released on May 1, 2007. The printed size is 130, and the checklist is the same length. Snorlax is 37/130, in position 37 of 130 on this checklist. Before it is 36 Purugly, and after it is 38 Steelix. The listed rarity is Rare.
Snorlax is a Basic Colorless Pokémon with 100 HP. The card lists level 35. In the Pokédex this is Snorlax (#143), generation 1 (Kanto).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Snorlax (#143) has 55 other cards in the catalog. Those other cards are in 42 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Snorlax 11/64 in Jungle (1999). That card lists 90 HP, and this one lists 100 HP. The rarity there is Rare Holo, and here it is Rare. 50 other cards of Snorlax list a different HP.
The attack Block lists no damage number. The cost is Colorless. The Defending Pokémon can't retreat during your opponent's next turn. Ease Up is another attack lists 40+ damage. The cost is Colorless, Colorless, Colorless, Colorless. Snorlax is now Asleep. If Snorlax is evolved from Munchlax, this attack does 40 damage plus 30 more damage. Weakness is Fighting +20. Retreat cost is 4. The flavor text reads "Its stomach can digest any kind of food, even if it happens to be moldy or rotten."
I keep a set binder for Diamond & Pearl, meant to hold every card of that set. This card is one slot in the Diamond & Pearl set binder. A generation binder holds one card of each species. Snorlax can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Snorlax and Munchlax. I still need this card.
