- The running gag of this episode is that Mr. Saturday keeps asking for a smoothie, his favourite drink.
- The title of the episode is a reference to the Mission: Impossible franchise
- Kord warns Eli about performing a fusion shot without the Enigmo's aid because it is the slug that enables a slinger to see Slug Auras that can aid him/her to make compatible fusion shots as seen in "The Return".
- The Slugball Championship shown on the television in Rusty Buckle Cantina is the same from the episode "Slugball".
