If this Baby Pokémon is your Active Pokémon and your opponent tries to attack, your opponent flips a coin (before doing anything else required in order to use that attack). If tails, your opponent's turn ends without an attack.
Flip a coin. If heads, your opponent's Active Pokémon is now Paralyzed.
This attack does 40 more damage for each Energy attached to your opponent's Active Pokémon.
