This troper (aka philipnova798), knows the fine line between staying consistent and being off model. That said, it happens a lot. While staying mostly consistant, problems with
Paul's (A crustacean) head spikes and claws,
Dogged nice guy (or
Deadpan snarker, depending on his mood) Peter's (a swordfish) nose and
Potty and Audrey Jr.'s (Plants) Chin placements (Potty has an overbite, Audrey Jr. has an underbite, which tend to switch fairly often) occur fairly often. Other minor things include
Haley's hair length and eyes,
The Pac-ghosts (known as the Ghost Mafia) heights,
Spybot's head when viewed from different angles along with other minor details like proportions, head shapes, line thickness and hand positions. Also parodied with with a character known as Gus, who's basically a walking, talking mistake. Did I mention that this series takes place in a (Fictional) town in Arizona with a Lion for a mayor? It's also worth pointing out that the off model effect was worse when the characters were first made (No one looked the same twice... at all. For instance; Peter would had thin limbs, thick nose and large in one panel and in the next panel, a smaller head, a shorter & stubbier nose and proportions that would make even the worse artists cry in pain, hence the idea of Gus)
