While a lot of fun to collect, many players blame the arrival of "secret" avatars for the downfall of the Neopian economy. A formerly-affordable item will rise to hundreds of thousands of Neopoints (the site's currency) just because an avatar was released to go with it. An example is an item known as a "Quadrapus": it was worth 20,000 Neopoints at the start, which is quite cheap. However, now you cannot get one for under 350,000 Neopoints at the time of writing, because it can give you an avatar. This can be very frustrating, as it is difficult for the average user to earn Neopoints on the site, and even more difficult for them to purchase items when sellers get greedy and inflate such items to immense proportions over a square of pixels. Before avatars arrived, many items were more affordable than they are today. One item- 200,000 Neopoints before its avatar was released- has even risen to 30 million Neopoints (at the time of writing)!
Avatar Collectors: "Look, a new avatar! We must have it!"
Avatar Collector: "Something Has Happened! You are now eligible to use "Blorpulous - Spooky" as an avatar on the Neoboards!"
Avatar Collector: "You need to have a 60-day-old Blorpulous attached to your pet, then view its lookup ^_^"
What will inevitably happen-
Sellers: *buy up all the cheap Blorpulous, then re-list them for 200,000 Neopoints each, effectively preventing your average Neopet user from obtaining one anytime soon due to the demand of avatar collectors who heavily collect Neopets avatars*
