Princess Bala: I sure hope you know what you're doing.
Z: Yeah, me too.
Mosquito: What if, like, we're just these tiny things... and we're just, like, part of this whole other huge universe... that's, like, so big we don't even know it exists?
Ladybug: Man, that is so deep.
Azteca: All we are saying is give Z a chance.
Weaver: Don't you want your aphid beer?
Z: Call me crazy, but I have a thing about drinking from the anus of another creature.
