In "The Fire Breather," when Chowder returns home, he finds Mung with a new apprentice who resembles the old Hanna-Barbara cartoon Droopy Dog.
The snacks Mung Daal and Shnitzel buy in the circus are churros, an actual Mexican dessert consisting of a stick of flour coated with cinnamon and brown sugar, and filled with hot applesauce.
This is the first time the characters speak with Spanish subtitles.
During the Fireheart song montage in "The Fire Breather", there's a quick image of Chowder and Panini on top of a volcano. They are dressed similar to that of the famous "Beast Master" movies.
