Revealing mistake: Susan appears to pass right through the glass window after knocking down Gallaxhar.
Monsters vs Aliens (2009)
1 revealing mistake
Directed by: Conrad Vernon, Rob Letterman
Starring: Kiefer Sutherland, Reese Witherspoon, Seth Rogen, Hugh Laurie, Will Arnett
Continuity mistake: It's shown in many scenes that the robot Gallaxar sends isn't particularly quick moving when it walks. But when it's chasing Ginormica around the city, even though Ginormica is sprinting away, it can catch her far more quickly than its speed would allow. It doesn't suddenly speed up - in the shots when the camera focuses on the robot again, you can still see it moving slowly.
The Missing Link: She's speechless.
B.O.B.: She"? It's a boy; look at his boobies!
The Missing Link: We need to have a talk.
Trivia: Keep watching the end credits, there are additional scenes.

Chosen answer: Well, it's a fiction movie; some suspension of disbelief is always needed. There could be a number of explanations: for instance, lifeforms such as insects on the grass, bacteria inside them or even grass itself, being unable to absorb quantonium. It might affect only sentient beings. Or Susan might even be the first being to get in contact with the substance - this would be possible depending on the shape of the meteorite container, the exact means by which quantonium touches her body - which isn't shown... but, first and foremost, this happens because its not happening would leave the filmmakers with a plot issue to be dealt with - so, other beings don't grow simply because they don't.
