Play some top-rated games. Kass Basher is usually a favorite game. Also, try Fashion Fever. You can earn 900 NP automatically, and if you send a card, you can get 1,200 NP. Don't forget to play the Featured Game. That game doubles your NP earnings on that game only.
It depends what paintbrush you want to get. For example, the Christmas PB (short for paintbrush) is relatively cheap for some users. It, on average, cost about 30,000. That 30K paintbrush is one that is given out in the Advent Calendar, located in Terror Mountain. That paint brush is very cheap compared to the 12,000,000 NP Relic Paint Brush. Also, be sure that your Neopet is compatible with that color. These paintbrushes can also be found via Random Event (RE) or by some dailies. Here is a list of
paintbrushes. That list has petpet paintbrushes also.
Some colors can't be painted. They must be zapped by the Lab-Ray (by collecting
these pictures),
eat a magical fruit pop, or
drink a potion.
If you're lucky, a RE can change your pet's color. Boochie, a Baby Bruce, can zap your pet, turning them only Baby.
Something has happened!
Oh no! Boochi fires his ray gun and turns [pet name] into a Baby [species name]!
Sometimes, he misses, so the chance is even less likely. Also, a torrent of multi-coloured water can fall from the sky, turning them into a random color.
Something has happened!
A torrent of multi-coloured water falls from the sky and DRENCHES [pet name]!!! You hear evil cackling from the sky... [Effect: Turns your pet a random color.]
There is even one that turns your pet invisible.
Something has happened!
Oh no! Where on earth is [pet name], you cant find him anywhere!!! Where on Neopia could he be? [Effect: Changes the color of your pet to Invisible.]
