You don't.
The only way you can is by making another neopets account.
The Petpet Plaza is found by easily looking in your map on Petpet park.
You make another account.
To make a new Petpet, simply just register and create a new account. Just be sure to make only 5 accounts as Petpet Park does not want users to create more then 5 accounts.
You can use your Neopets account for PetPet park.
Petpet Park was created in 2008-10.
At the Petpet Emporium.
