Corrected entry: At one point, one of the Penguin's clowns kidnaps the mayor's baby, and drops into a sewer to hand the baby to The Penguin. As we peer into the sewer, we see that it's a narrow stone shaft. The Penguin then slowly emerges from the manhole from one of the ducks he keeps in the sewer. He would not have been able to emerge as far as he did even if he stood on the duck's head.
Corrected entry: On Wednesday, Selena completely destroys Shreck's department store and by Saturday night they have a grand Christmas masquerade ball in the same store.

The milk was never put back in the fridge when she left her house the first time.
