During your opponent's next turn, whenever Chikorita takes damage, divide that damage in half (rounded down to the nearest 10). (Any other effects still happen.)
If the Defending Pokémon attacks Chikorita during your opponent's next turn, any damage done to Chikorita is reduced by 10 (before applying Weakness and Resistance). (Benching or evolving either Pokémon ends this effect.)

Flip a coin. If heads, then if, during your opponent's next turn, Phanpy would be Knocked Out by an attack, Phanpy isn't Knocked Out and its remaining HP become 10 instead.
