- Conan O'Brien's death in the sequel. He is impaled through the back by one of Sharktopus' tentacles, the end of it sticking out of his mouth. His head is then bitten off and chunked over towards some volley ball players, who use it as a volleyball.
- Pteracuda pimp-slaps Sharktopus twice in their first encounter. Later Sharktopus gives Pteracuda a few Three Stooges smacks in return.
- In the third movie at one point the "hero" is lost in a mall. He looks at a mall map and asks, "Where am I?" A clawed tentacle promptly reaches up over the map and lightly taps on the 'You are Here' mark.
