+## Pokecenters Disregard Eggs
+
+In Gen4+, pokecenters disregarded eggs for the healing animation. This replicates that effect in Pokeemerald
+
+### Replace the relevant party count
+Open [src/field_effect.c](../blob/master/src/field_effect.c). Change [line 982](..blob/master/src/field_effect.c#L982) to:
+```c
+nPokemon = CountPartyNonEggMons();
+```
+
+### Allow field_effect.c to recognize `CountPartyNonEggMons`
+Keep [src/field_effect.c](../blob/master/src/field_effect.c) open. Add the following somewhere at the top:
+```c
+#include "pokemon_storage_system.h"
+```
+
+### Make `CountPartyNonEggMons` a global function
+Open [include/pokemon_storage_system.h](../blob/master/include/pokemon_storage_system.h). Add the following to the bottom:
+```c
+u8 CountPartyNonEggMons(void);
+```
+
