NeoDevice

NeoDevices are similar to Digivices, but only hold Neopets that a human has befriended. NeoDevices can come in different colors depending on how the human partner's bond with his/her Neopet is.

Colors
The only known NeoDevice is a green-colored NeoDevice owned by Jim. But it is said that NeoDevices can come in different colors. Once a human befriends a Neopet, they receive a NeoDevice which shows that they bonded with their partner Neopet.
