The first way (and best way, if you have a little over one million NP, but below 1.5 million) to get a Krawk is to buy a Krawk petpet.
First, make sure that you do not have 4 pets, otherwise, you can't get a Krawk. :( Then, go to the Trading Post or the Auctions House and type in Krawk (make sure you enable identical to my phrase!) and put a bid on the auction/trade.
After you're bought the Krawk, attack it to your pet, and name it by going to the Quick Refs page. This will be it's name when it becomes a pet. Then go to the Fungus Cave and feed it some Magical Fungus. Hooray, your Krawk petpet is now a Neopet!
Here are some important things to remember:
- The Krawk Petpet will cost around 1 million NP, give or take a few hundred thousand.
- If you painted your Krawk with a petpet paintbrush, it will be that colour when it becomes a Neopet. (eg. Red Krawk Petpet -> Red Krawk Neopet).
The second way (and best way, if you have over 1.2 million NP, and want a mutant Krawk) is to buy a Krawk Transmogrification Potion for your Neopet, and feed it to your Neopet so it becomes a Mutant Krawk.
The third way (and best way, if you have over 2 million NP and like morphing potions and customization) is to buy a Krawk Morphing Potion. Go to the Trading Post/Auction House and look for Krawk Morphing Potion with "containing my phrase" on. The good side about this is that you get to customize the colour of your wonderful Krawk, but the bad side is that it's really expensive.
If you're wondering if I have a Krawk, that's a no. Scorchios' are my favourite pet and Krawks have never really been on my list of cool Neopets. XD
