A Stage 1 Pokemon Card of type Grass with the title Koga's Kakuna and 60 HP of rarity Uncommon evolved from Koga's Weedle from the set Gym Challenge.  It has the attack Toxic Secretion with the cost Grass, the energy cost 1 with the description: Flip a coin. If heads, the Defending Pokemon is now Poisoned. It now takes 20 Poison damage instead of 10 after each player's turn (even if it was already Poisoned). It has the ability Emerge with the description: Once during your turn (before your attack), you may flip a coin. If heads, search your deck for an Evolution card named Koga's Beedrill and put it on Koga's Kakuna. (This counts as evolving Koga's Kakuna.) Shuffle your deck afterward. This power can't be used if Koga's Kakuna is Asleep, Confused, or Paralyzed. It has weakness against Fire 2.
