Any damage done to Kakuna by attacks is reduced by 20 (after applying Weakness and Resistance).
[G] Dangerous Evolution
The Defending Pokémon is now Poisoned. Flip a coin. If heads, search your deck for an Evolution card that evolves from Kakuna and put it onto Kakuna. (This counts as evolving Kakuna.) Shuffle your deck afterward.
While awaiting evolution, it hides from predators under leaves and in nooks of branches.
