You can get a free paint brush on neopets by either going to the giving tree or by trading with someone.
You can't! Unless someone gifts you one or you get it in a random event there is no where to get a free baby paint brush
A brown paint brush in Neopets is worth about 600,000 neopoints
Not at the moment... You can only get mutant from the lab ray.
You can trade for them on the trading post or random events.
You buy one from a shop. Usually 40-50,000 neopoints.
The starter can't be traded (sold, traded, auctioned, donated). so you have to either use it in the rainbow fountain ( located in Neopets Central)or discard it. The normal one can be traded or used or discarded.
Buy the baby paintbrush and then go to the rainbow pool and paint the desired pet.
One way is to spin the wheel of excitment in faerieland, the wheel of knowledge in brightvale, the wheel of monotony in tyrannia, or the wheel of mediocrity in tyrannia. (you have to pay to spin the wheel. sorry ): ) Another way is to play key quest, earn a gold or silver key, and get your price! ( you can also get neopoints.)
You should try the trading post. There are loads on there and although they are quite expensive, they are very worth it!
with a paintbrush, morphing potion, or secret laboratory map...or Boochi which is a random event.
You can find paintbrushes by either looking it up in the Marketplace, OR when your lucky, you will get a paintbrush by random events.
the lab ray- it's the same as jelly pets.
