Note: Not everything is going to be in airing order, so correct me if you feel it's necessary. I'd add this as a page, but nobody answered whether it was a good idea, so here it is as a blog.
The names of certain characters will be in the "Heading" format. Then the episodes will be in sub-heading 1.
Ord[]
To Fly with Dragons[]
Reason: The gang still hadn't found his lost baby tooth.
The Forest of Darkness[]
Reason: He was too scared to enter the eponymous forest.
Snow Dragons[]
Reason: He and Max were lost.
No Hitter[]
Reason: Max kicked him in the tail.
Big Funky Cloud[]
Reason: He had lost his blanket forever.
Breaking Up Is Hard To Do[]
Reasons: Max stepped on his foot. Later, after Zak split his and Max's art project, they both found out that it didn't work like it did as a whole project, and Ord now has nothing to show his mother.
Cassie[]
Goodbye Little Caterpoozle[]
Reason: She believed Poozy was dead.
Emmy's Dream House[]
Reason: Emmy changed her (Cassie's) bookshelf to suit herself.

Cassie Loves a Parade[]
Reason: She didn't get picked for the book float in the School in the Sky parade.
Bully for You[]
Reason: Spike was mean to her.
Zak[]
Quibbling Siblings[]
Reason: Wheezie's loud noise had scared the jugglebug, an already-rare animal, leaving him nothing to share at school.

Emmy[]
No Hitter[]
Reason: Max punched her in the arm.
Enrique[]
Feliz Cumpleaños, Enrique[]
Reason: No matter how hard his friends worked to give him a nice party, which he appreciated, he missed those he had back in Colombia really badly.
(NOTE: Of course, he had been given the "Big boys do not cry" message, but Quetzal encouraged him to cry anyway.)
Priscilla[]
The Ugly Dragling[]
Reason: The gang stared at her feathers, which she was ashamed of.
Mungus[]
Just Desserts[]
Reason: The gang bounced on his wiggly-jiggly dessert (which he made as a birthday treat for his mother).
Trumpy the Troll[]
Head Over Heels[]
Reason: He had been making anyone wanting to cross his bridge do cartwheels, which was because he had never learned how.
Cosmo[]
Cassie Loves A Parade[]
Reason: He had not been picked for the book float, just as is true with Cassie.
Kiki[]
Baby Troubles[]
Reasons: For one, she is a baby. Then there was the problem with Ord accidentally squishing her squishy.

Reason: She was separated from her parents.
Am I missing any other times?
