- Cross-Dressing Voices: Goomzilla uses a high-pitched voice for Lady Bow.
- I Knew It!:
- In Luigi's Quest, people have correctly guessed a number of things that Solus is evil all along, that he was a Dry Bones this whole time, given that there were clearly grey hands and boots to match the Dry Bones plush used, and that the way Peach would be "made more loyal" to Bowser was through hypnosis.
- Peach Quest has some of this too. It was obvious that the Toad that helped Peach in the beginning would turn out to be a Duplighost, given his suspicious behavior, and that the leader of the Duplighosts would be Mimi.
- Name's the Same: The Goomfrey that appeared in Mario's Quest is not the same Goomfrey from Paper Mario: The Thousand-Year Door.
- The Other Darrin: Bowser Needs Minions was the first episode to feature a brand new Peach plush.
- Schedule Slip:
- Part 3 of Luigi's Quest took almost a year to release due to Goomzilla going to university around that time.
- Now that Goomzilla is working a full time job, these might happen more often. As such, part 3 of Peach's Quest took over half a year to make. Though part of that may also be due to how long it was compared to his other videos, and the Special Guest in that particular part.
- Talking to Himself: With the exception of Toadette and Mimi, Goomzilla has voiced for almost every character that speaks. So naturally, fully-voiced characters that speak to each other fall into this trope, especially if their voices sound similar (i.e. Kamek and Solus).
- Throw It In!:
- The Mario Bros.' house tumbling over in Bowser's Mushroom Factory was an accident, but it made Goomzilla and his sister laugh, so they made it a plot point, not thinking anyone would watch the video anyway.
- Luigi kicking Wario and Waluigi's furniture in Yoshi and the Lost Egg was an accident, but Goomzilla kept it in because he felt it showed how little he cared for their possessions.
- What Could Have Been: Yoshi and the Lost Egg was Goomzilla's first interactive video, but it was originally meant to be Wario the Bankrupt, where viewers would choose what job Wario should apply for, until he scrapped the idea for something more simple.
