You can only get the starter token and some special tokens from the site, for all others you must by a real life plushie/toy and type the code into the grundo warehouse and you can receive a new token.
if you mean the key quest tokens, there's a code for them on almost all neopets merchandise, including the burger king neopets plushies, but i think burger king isn't doing it anymore.
By planing and winning the Key Quest game
The answer was Key Quest.
buy a plushie for real
I got my key quest tokens from playing various games like the recent daily dare challenges :) check out my collection.... Starsong001
Find all the pieces of the pepet lab. map. This can be random OR, you can get a random one in key quest.
The best place to get paintbrushes on neopets is doing the keyquest with 5 keys and 2 players. If you win and get a golden key sometimes you earn a paintbrush
If you login to neopets, use the top navigation menu where it says GAMES. A window should appear when you hover over Games, and Key Quest is one of the options. An alternative is to go to games and search for Key Quest (though it is usually on the main Games page). Another alternative, this will take you directly to the main page: http://www.neopets.com/keyquest/redeem.phtml Once you arrive on the main Key Quest page you will see a box on the right-hand side of the page where you can enter your Key Quest redemption codes.
It uses a key but no compass. You can go from the dragon to the village and the forest to the Goblin King. You can also earn the key.
Lots of work, couple of random events and lots of work. Key Quest helped me a lot. Also a lot of work...
You can purchase different character game pieces with neocash and redeemable codes. Yes, it is lame but you can't buy them with neopoints.
You have to get one yourself.If you see one online you will most likely not be able to use it because it has already been redeemed by someone.
