The pet was offered as an incentive to get people to join the Firefall community. With each e-mail referral earning you 20 (figurative) Crystite and each accepted referral (with account creation) earning you 200 Crystite. When the account had earned 440 of the Crystite from referrals, a Merch pet was issued to the account.
The joke behind the pet is that poor players with the pet would have the pet reflect their lack of funding by having it's mood change. While no official figures were given, players were able to determine the values to be the following:
|Mood||Crystite in your Inventory|
|Sick||1,500 - 4,999|
|Angry||0 - 1,499|
While spending Red Beans can encourage it's mood to change, it is presently unknown to what degrees or extents the mood will change.
