Factual error: In the sequence where the animals get on the first subway, it says they are on the 59th St subway. But, there is no 59th St subway in NY. The only subway station close to 59 is the 57th St subway.

Suggested correction: There is definitely a 59th street subway station: https://en.wikipedia.org/wiki/59th_Street_ (BMT_Fourth_Avenue_Line).
