Accidental Innuendo: The Little Bees keep going on about their stingers, and one of the Little Cars says that the Champion gets her motor running.
Alternate Character Interpretation: The mouth of Amanda from Little & Big Monsters defaults to a smile regardless of what her eyes are doing, so she always looks like she's either on drugs or cooking up some diabolical scheme.
Memetic Molester: This seems to be Video Brinquedo's interpretation of the Frog Prince. In his eponymous movie he's a slimy Manipulative Bastard who acts like he's entitled to have the princess just because he helped her out of a situation he caused. In Little Princess School he tries to rape the princesses' teacher.
Nightmare Fuel: The Greaster Car from The Little Cars Easter special. This automotive abomination has a white ghostly body with bright red eyes, a voice normally heard from psychopathic man-children, and appears in the dead of night by a lake that isn't really there.
Special Effects Failure: They're pretty much this to the entirety of the full CG animated movie genre. In other words, they're the polar opposite to Pixar.
A stand-out example happens in The Little Cars. The villain cheats at the race by dropping some tacks on the road, causing one of the racers to spin out of control. The race ends with him not paying attention and running over his own trap. However, the animators forgot to add the tacks to the scene where he drops them, so what happens instead is that the camera randomly cuts to a shot of the villain's taillights before one of the other racers suddenly spins off the track for no reason. The race ends with the villain running over some tacks that just happened to be sitting on the track.
Uncanny Valley: The animation is very stiff and this is most noticeable on characters' faces. Even though they're not supposed to look like humans, they still don't look right.
The extras, announcer, and Shallow Love Interest in The Little Panda Fighter have human figures with crude bear heads and no textures. They look pretty creepy. Polaris's abs are similarly unnerving.
