Every Little Vote Counts (S02E03)

The Littles are eager to enjoy the outdoors, but the mayor refuses to allow it due to the threat posed by Dr. Hunter and his traps. When a phony character called Smiling Al arrives and decides to run for mayor, Tom, Lucy, and Grandpa work tirelessly to ensure the current mayor is re-elected. However, Smiling Al takes advantage of the situation by granting the Littles access to the outside world, which leads them straight into Dr. Hunter's traps.
