When Zak and Wheezie about to go to Chilly, their entire tail is green, instead of purple and green.
In "A Snowman For All Seasons," it stopped snowing, but that doesn't mean that it got above the freezing point. It doesn't have to be snowing to be cold, and it doesn't have to be very cold for it to snow. Sometimes Chilly & Nippy could melt even when it's snowing very heavily!
In "Dragonberry Drought," Cassie states that she has 72 brothers and sisters. This is an alteration from past episodes (Season One), in which she stated that she has 74 brothers and sisters.
Max: Look! Over by the lagoon! Isn't that a RED circle?
Ord: You found one, Max! Oh, you're the best! (dreamily) I can already taste those dragonberries all tummy in my tummy! Mmmm....
Max: Man, I'm stuffed!
Emmy: Me, too. I'm so full that I won't be able to eat again for three whole weeks. (Echoing back to 'A Crown For Princess Kidoodle' in which she states that she won't be able to eat again for three days.)
Chilly and Nippy appear again in the episode "Rise and Bloom / Super Snow Day".
The dragonberry seems reminiscient of the commercial for Oops! All Berries in that they messed up and put all the berries in one cereal.
