Questions as to what Pokémon waits inside the egg Ash and friends have been carrying for Professor Elm are finally answered when it hatches into a Larvitar. Our heroes hardly have time to celebrate, however, as they realize that this Larvitar is unwell, its body temperature much lower than normal for any non-Ice Pokémon. Even at the Pokémon Center, Nurse Joy is unable to do anything to stop this Larvitar’s body temperature from dropping even further. Just as she warns Ash that Larvitar’s life may be in danger, problems are compounded by a sudden and unexplained blackout. Desperately, Ash and friends set out to restore power to the Pokémon Center in time to somehow treat their ailing Larvitar.
