By Khyber's Pet
- When Ben is about to slam the Omnitrix for Crashhopper, the screen on the Omnitrix is sideways instead of straight.
- When Wildmutt tackles Buglizard, he roars without his mouth moving.
- Khyber's "Yes" quote at the end of the episode is a reference to how Megatron from "Beast Wars" always trolls on the word "yes".
