Even though they have the ability to combine to solve their problems, there's no doubting that sometimes, the Mixels can be pretty mindless.
- In "Coconapple", Zorch mixes with Seismo in order to help him get his coconapple. The mix even strikes a heroic pose.
- You'd Expect: The mix would fly heroically (or at least try to control its flight speed), thus getting the titular coconapple which Seismo wanted.
- Instead: The mix flies uncontrollably like a malfunctioning helicopter, recklessly crashing through some homes and even getting stuck in a volcano.
- As A Result: Seismo doesn't get the coconapple he wanted. Zorch ends up being the one to get it.
- In the "Only You Can Stop Forest Freezes! Only You!" Segment of "Mixel Moon Madness", after Meltus accidentally melts the Camp Cube, Bernard gets some ice water to chill it back up, only for him to get chewed out by an angry Flamzer.
- You'd Expect: Flamzer would snatch the ice water out of Bernard's hands, put the lid back on, and put the ice water away.
- Instead: Flamzer refuses to put lid back on or even turn it upright, causing the ice water to pour onto the floor.
- As A Result: Flamzer starts a forest freeze and nearly gets frozen solid if it wasn't for Bernard and Meltus's quick thinking.
