// The data are u16 instead of u8 for reasons unknown.

// sWhiteoutRespawnHealerNpcIds
// When you respawn, your character scurries back to either their house
// or a Pokémon Center, and hands their fainted Pokémon to their mother
// or the Nurse for healing.
// This array defines the index of the NPC on the map defined above
// with whom your character interacts in this cutscene.
