Blackberry onix
you make them with berries
Just use super rare berries to get gold pokeblocks.
You can make pink pokeblocks by using sweet berries. For example: Pecha berry
oran berries You can get a pamtre berry only once from the berry master's wife, by telling her "challenge contest". It makes very high level beauty pokeblocks.
get rare berries and cook them to perfection
Feed them good pokeblocks from durin berries.
You can make pokeblocks at any contest hall i would suggest blending berries at lilycove city's contest hall.
You can't keep one personally but you can use them in contest halls. Then, you can make pokeblocks. But first you need a Pokeblock case to keep all pokeblocks you make. You would need berries. Lots and lots of berries.
Yes, makes it more orange
when you are done making pokeblocks from berries go to ur bag and select key items and then go to pokeblock case and click open. choos the pokeblock and then the Pokemon to feed it too.
It took me 6 kelpsys and 1 wiki (pokeblocks made in lilycove)
