Jungle is a set in the Base series. It was released on June 16, 1999. The printed size is 64, and the checklist is the same length. Mr. Mime is 22/64, in position 22 of 64 on this checklist. Before it is 21 Kangaskhan, and after it is 23 Nidoqueen. The listed rarity is Rare.
Mr. Mime is a Basic Psychic Pokémon with 40 HP. The card lists level 28. In the Pokédex this is Mr. Mime (#122), generation 1 (Kanto).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Mr. Mime (#122) has 34 other cards in the catalog. Those other cards are in 29 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Mr. Mime 6/64 in Jungle (1999). Both list 40 HP. The rarity there is Rare Holo, and here it is Rare. 32 other cards of Mr. Mime list a different HP.
Invisible Wall is listed as Pokémon Power. Whenever an attack (including your own) does 30 or more damage to Mr. Mime (after applying Weakness and Resistance), prevent that damage. (Any other effects of attacks still happen.) This power can't be used if Mr. Mime is Asleep, Confused, or Paralyzed. The attack Meditate lists 10+ damage. The cost is Psychic, Colorless. Does 10 damage plus 10 more damage for each damage counter on the Defending Pokémon. Weakness is Psychic ×2. Retreat cost is 1. The flavor text reads "If interrupted while miming, it will slap around the enemy with its broad hands."
I keep a set binder for Jungle, meant to hold every card of that set. This card is one slot in the Jungle set binder. A generation binder holds one card of each species. Mr. Mime can fill a slot in Generation 1 binder (Kanto). I still need this card.
