To add the Neopets ‘Alien Aisha’ avatar to your collection, you need to use a Nerkmid at the Alien Aisha Vending Machine. Nerkmids can be obtained by battling the Space Jetsam as a Premium member, or alternatively they sell for between 50,000nps – 90,000nps in user shops. They are more expensive to buy in the first week of each month. Click here to go to the vending machine.
