At one point, Sanson throws a fit about being sick and tired of eating "fish, fish, fish, fish, FISH!!!!" before finally settling down into a more deadpan "All in all I have to say I'm a bit tired of the fish.
Both Electra and Nemo tell Grandis (when she wears her bikini suit) "At your age, you could catch a cold in that!"
The Grandis gang hug each other and bawl hysterically when they're imprisoned in the Neo Atlantis compound, mainly when the prison soldier tells them that they'll end up decomposed just like their "neighbor" in the next cell. However, after the guard leaves, all three stop crying and loudly declare, "Just kidding!"
Any scene where Grandis and Electra are arguing with each other has some hilarious exchanges.
