Jelly World
In a very distant corner of Neopia, a strange town exists built entirely of orange jelly. Nobody knows how it got there, perhaps a magic spell that backfired, or perhaps it was commissioned by an eccentric Neopian billionaire with a sweet tooth, who knows!
The first reference to Jelly World was in the New Features section on 30th March 2002, where it says "... and of course the upcoming new world 'Jelly World' ...". Countless times The Neopets Team has denied the existence of Jelly World. It is their own little secret :)
Jelly World has had several links to by people claiming it exists, including one in a quote by Prisoner Five in Cellblock, but the real link is: http://www.neopets.com/jelly
The most notable attraction is the Giant Jelly, simliar to the Giant Omelette in Tyrannia, but each plate of jelly only gives out two servings.
