Currently - to fill my stamp album. Then complete my galleries. But honestly, I like having galleries to fill because it makes me actually want to do something other than just click around.
I would probably do random acts of kindness. lol. I do that now with what I have sometimes too.

I would train my stats to like 100k + hp for the lols. I would get every super powerful bd weapon and possibly make a gallery of pricey and rare bd weapons.
The only thing I can think of is increasing my avatar count and owning one of every UC neopet species and colour. And perhaps creating an epic userlookup, custom coding, maybe a nice gallery... not much point in item goals though if you have unlimited neopoints since anything would be attainable
