Clarence Wiki
"We're working on something???"
This is only used on pages that are not related to either the episode, characters, or etc, so please be assured that this is a experimental, so it's not complete yet.

The following page is a list of goofs, mistakes, and animation errors in the series Clarence.

NOTE: There is a difference between a goof (a mistake made by the show's writers/producers) and an intentional gag shot (a mistake made by a character, or as a joke or reference).



  • The colors of Debbie's shirt, hair, and shoes change right before Clarence hands out his custom invitations.

Fun Dungeon Face Off[]

  • When Clarence finishes eating his food, there is a large ring of ketchup around his mouth. Shortly later, when he and Sumo enter the Fun Dungeon, the ketchup ring suddenly disappears. An error similar to this appears in "Plane Excited".
  • When Clarence takes off his shoes before going into the Fun Dungeon and swaps them with a girl's pink pair of shoes, he puts them in the top-right corner. Later on, when the little girl is seen sobbing after learning that her shoes were stolen, his shoes appear to be in the cubby on the right. A few minutes later, when the janitor is buffing the floor, his shoes are now in the middle cubby.

  • At the beginning of the episode, Clarence and Sumo sit down on the sidewalk and pick some food off and consume it. At the next scene after Jeff said about Belson's new game system, Clarence and Sumo have a mess around their mouths. But at the next scene, the mess disappeared. The possibility is Clarence and Sumo might wipe it off when they are off-screen. Also, the mess magically appeared when it did not even show Sumo eating ketchup.
  • When the screen zooms out and shows the environment at the beginning, Sumo was sitting on the sidewalk beside Clarence's right side. But then Sumo mysteriously appeared to be walking of Jeff's left side.

But instead, Chimney (the dog) brought a bunch of sticks to them as a way to "help". When the boys are seen again in the well, now surrounded by sticks, Sumo and Clarence switched spots. Sumo was now below Clarence. Given that Clarence's size is much to big and bent in a weird position, he couldn't have moved.
