- Queen Halbert is captured in the Capture Cruiser by Ruina Stoneheart, referencing the set 70349 Ruina's Lock & Roller.
- This episode was recorded in 2016, based on an image released on Facebook by Heather Doerksen showing the Nexo Knights cast including Lisa Bunting, who only portrayed a character in this episode. However, Noel Johansen and Michael Daingerfield seem to be missing from the photo.
- This marks the first appearance of Hadda Hammerin, Ruina Stoneheart, the Capture Cruiser and Hotspur.
- Clay succumbs to his illness beginning in "A Little Rusty," turning him to stone.
- Jestro refers to the evil plan as his, and Monstrox tells him it is theirs. This is the opposite of what usually happens, Monstrox taking the evil plan as his.
- In one scene, Hadda Hammerin's lipstick is missing.
- When the Harpies say "That's right, we are, deal with it!", none of their lips move.
- When Roog says "We got the Rogul, now, trash the rest of this place!", he speaks with Reex's deeper voice.
- Rumble's facial expressions stay mostly the same throughout the episode.
