Question: Is there any reason why the EPA couldn't just put the dome over the lake instead of the whole town? I mean, the only thing that actually is causing any pollution is from the lake.
Question: Didn't anyone notice Maggie, Lisa, Bart and Marge jump from the treehouse to the sandbox portal without anyone from the very large mob noticing? It seemed like nobody noticed until Homer jumped in and got stuck initially. Everyone in the mob were around the sandbox, how come no one noticed the other four Simpsons jump?
Question: First of all who is the EPA guy and what does he have against Springfield? Secondly, What happens to Spiderpig? Halfway through the movie they just cut him out.
