I mean, in here dragons are practically the same as us looking at ants (although I don't know about the comparison since I find they're fascinating creatures even though they creep me out), so destroying them because of a cake may seem absurd to both humans and dragons, but it's just like "those dudes pissed me off then destroy them", that's how much insignificant humans are in their eyes I guess ? It's just seem pointless to try understand their POV.
It's a bit ridiculous but has enough of the velocity to launch itself to the orbit. Even if it loses an arm or two, it still has legs to support itself. Sometimes you just read it because the artwork is making up for the rest.
