These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Jerkass Woobie: Urpgor is a psychotic weasel who constantly relishes in any torture Blob and his minions recieve; however, his right hand role with Zordrak only leads to him suffering even more abuse and pressure from their boss, and, despite his beliefs, is considered no less despensible than the other Urpneys because of it. Naturally whenever he tries getting the stone instead of Blob, things usually go just as well too.
Periphery Demographic: The show is fairly cutesy and childish in tone (cartoon hosting site Jaroo even lists it as a Pre School show) however it has gained more than a few older fans, largely for it's witty Urpney humor.
Rewatch Bonus: Rufus' dream sequence in the pilot episode actually alludes to some events in later episodes (the three shooting stars that the jettisoned Urpneys create in "The Daydream Bubble" along with the eventual reveal of Planet Dreamstone throughout the former and "The Dark Side").
Straw Utopia: The Land Of Dreams is incredibly peaceful and void of conflict and woe outside when the villains attack. Viltheed tries to act as a Straw Dystopia, but the Urpneys' sympathetic disposition counters it.
They Wasted a Perfectly Good Plot: The show has a pretty creative premise, though development of it's expansive universe, cast and mythos are often overlooked in favor of the Urpneys' slapstick taking up most of the spotlight, especially in it's earlier seasons. If it weren't for its name, The Dreamstone could often be seen as any other standard MacGuffin stealing show (not to say it's a bad one however).
Unintentionally Sympathetic: While the show already places a lot of intentional sympathy onto the Urpneys, their defeats are mostly designed to be slapstick and the heroes are designed very clearly to be of higher moral ground. However the Urpneys' damned position, which is either to face a brutal (and sometimes deadly) punishment at the hands of their Bad Boss or go to the Land of Dreams and inevitably get outfoxed and decimated by the sympathizing heroes, or often both, can come off as rather mean spirited in a particular light.
Vanilla Protagonist: The Noops, Rufus and Amberley, end up looking fairly unremarkable compared to the villains and even most of their more powerful and surreal comrades. They take the part well as newcomers encountering the show's different worlds and processes, but the focus otherwise usually sways in the Urpneys' favor due to their more colorful personalities and providing most the show's slapstick.
Wangst: The Noops really don't like getting bad dreams. The Dream Maker apparently has terrified mobs at his door the moment they get so much as one.
