** There are at least a couple of passing references to "Ragnarok" in the series, including "Ragnarok Canyon" and "Ragnarok Cheese." (Though, according to at least one book release, ''Hand in Hand in Dragon Land'', the actual spelling is "Rag-na-Rock.")
** The show was never really specific about whether time is effected in the real world while Max and Emmy are teleporting to Dragon Land and back. While most episodes they return to the playroom and it looks exactly like how they left it, sometimes the kids teleport to Dragon Land just as it's daylight at their house and return to the real world when it's nighttime. It just keeps alternating. Is time effected in the real world effected while kids are in Dragon Land?
** It goes beyond that. In one episode, Max and Emmy ''bring home a video recording'' from Dragon Land. What's going to happen when their parents find it?
** What'll become of the gang when Emmy and Max grow up? Are dragons even aware that human children eventually grow up?
*** Technically yes they are. Remember that pirate captain they met up with who had buried toys under the schoolhouse? He states the toys were his as a boy and he and Quetzal buried them as children. They're certainly aware that Quetzal is an adult or at least much older than them so they're aware that humans age/grow up.
* FridgeLogic: The four main Dragon characters are implied to have parents, who, if they show up, are shown to be much larger than them, and yet, Quetzal, a dragon much older than the four, is only about two feet taller than Ord. Ummmm....
** Miniature senior citizen?
** Or it could be part of Quetzal's Stealth Mentor gig. He probably intentionally represents himself as smaller than he is in order to better relate to the children as a guide so they don't treat him as a parent.
** It may also be because Quetzal is a teacher for young children. Ever notice how human teachers will try to get down to their students' level when possible. This might just be the fantastic equivalent, especially since we see the child dragons being able to alter their shape if they're the same basic type of dragon as Quetzal (single head) so it might be a racial skill.
