- Like the Ninja Turtles, they have oxygen converters as well that they use when the atmosphere of a place isn't what they breathe.
- The atmosphere in their planet contains nitrogen.
- If a Triceraton doesn't breathe pure nitrogen, they can become sick.
- The Triceratons being able to breathe nitrogen is a reference to the original comics and the 2003 Triceratons.
- According to the producers of the show, the Triceratons are 10 feet tall and 5 feet wide.
- This is actually how big a full grown Triceratops was.
- Their planet was destroyed by The Kraang millennia ago with the Heart of Darkness.
