Your opponent's Active Pokémon is now Asleep. During Pokémon Checkup, your opponent flips 2 coins instead of 1. If either of them is tails, that Pokémon is still Asleep.
During your opponent's next turn, the Defending Pokémon can't retreat. During your next turn, the Defending Pokémon takes 90 more damage from attacks (after applying Weakness and Resistance).
