After Quack Quack tries fruit yogurt, he starts to prefer it to plain yogurt. The plain yogurts turn to Olaf to help them wage a war against the fruit yogurts.
"Let's Play Yogurt War" contains the following tropes:
- Let's Meet the Meat: The yogurts interact directly with the characters. Olaf even lampshades how weird that is.
- Mandatory Line: The end of the episode has Mr. Cat coming outside to yell at everyone for making too much noise since he's suffering from Hangover Sensitivity.
