Does it eat any more pokeblocks?
Emerald version: use Pamtre beries. You get them if you say CHALLANGE CONTEST to the berry masters wife. You may only be able to get 1, but you can just clone a pokemon holding one. then you can have alot.
Ruby/Saphire: Trade the pokemon to emerald and do the above.
If you dont have an emerald though, then just breedit, get another one, get it one of those natures,and then use other berries that make high lvl Indigo pokeblocks.
Note: if you use the pamtre berries, use the berry blender with the 3 people there, making you the 4th.

othor possoble outcome:
