Boper's notes for later edits:
In November 2008, players outside of US and Canada were able to create a demo account on (now devoid) webkinzdemo.com, which allowed users to experience parts of Webkinz World on a 24 hour trial account offered in multiple languages. Demo accounts were created similarly through the Adoption Center, but were separate from the existing Webkinz World, so a username could be used on a demo account even if it was already used for a regular Webkinz membership. Demo players were able to adopt a boy Mutt (demo-exclusive pet) named Patches, which came with the PSI of a Red Dragster (alias of the Webkinz Dragster on full accounts) and PSF of a Burger and Bun (alias of Hamburger). The demo account also came with a Welcome Balloon, 5,000 KinzCash, some furniture, and a Wish Token (despite the fact that the Wish Factory was closed on demo accounts). The demo accounts were deleted after 24 hours.
Soon after, Ganz allowed US and Canada players to create a trial account through the regular Webkinz login screen. Players could choose between the Mutt or Domestic Cat (both trial-exclusive pets) and were allowed to choose their pet's name and gender (unlike the previous demo version). The trial pets did not come with any adoption gifts. In the trial account, players could only access a few hourly activities, 5 Arcade games, and a limited WShop. The trial account would be deleted after 24 hours, unless the player used a regular Webkinz pet adoption code to upgrade the account to a full membership. Once upgraded, the account had access to all of the same features as a normal Webkinz account, plus the ability to keep the trial pet. The trial feature was later removed.
In March 2012, the free account feature was reintroduced as a permanent free-to-play gamemode. Players were again able to choose between the Dog (previously called Mutt) or Cat (previously called Domestic Cat), which came with adoption exclusives of the Webkinz Dragster and Dog Burger (reused art from Hamburger) or Blue Ball Cap and Cat Chocolate Bar (reused art from Chocolate Bar). Only one free pet could be obtained per free account, therefore it is impossible for any account to have both free pets. These pets also do not have adoption codes, therefore it is impossible to adopt either pet onto an existing account.<--https://www.youtube.com/watch?v=5Sa39jLX1Fg-->
In August 2014, the Dog and Cat were replaced with nine previously released pets: Afghan Hound, Cotton Top Tamarin, Floppy Eared Bunny, Ice Fawn, Leonberger, Marshmallow Chipmunk, Pink Zebra, Sun Fox, or Wolf. These pets came with their traditional adoption exclusives.
In November 2016, the free account pet choices were: Afghan Hound, Floppy Eared Bunny, Himalayan, Ice Fawn, Leonberger, Pink Zebra, Sun Fox, Wintermint Reindeer, or Wolf.
In October 2018, the free account pet choices were: Afghan Hound, Big Top Elephant, Cotton Candy Sheep, Floppy Eared Bunny, Himalayan, Ice Fawn, Leonberger, Sun Fox, or Wolf. https://www.youtube.com/watch?v=Yx_LnjV96pY
Demo accounts were closed after 24 hours of existence. Trial Account History 2 Shortly after the Demo's retirement in the US, players were given the option to use a Trial account. Players could choose between the Mutt or Domestic Cat (also a Trial-exclusive pet), and they could choose their new pet's name and gender. The Domestic Cat did not come with its own PSI and PSF. In the trial account, players could only access a few hourly activities, 5 Arcade games, a few pieces of clothing, and not much else. Some players managed to adopt a pet before their 24 hour trial was up, meaning that they got to keep their Domestic Cat or Mutt.
Trial Account History 3: Current Day Today, it was discovered that the Free Account option was open again, even to members in the USA. Go to the Webkinz homepage, and click on the "New Member" button.
