If I remember correctly, they are to get new players used to using Paint Brushes without going into debt. If you go to the rainbow pool (link below) with the Paint Brush in your inventory, you will be able to paint your pet green. The item will then disappear.





Note: Certain items that you receive in your starter pack can not be used by anyone but you. Those items can not be sold or traded.
