In episode 3, the ZZZ Gang blackmails the awesomely mustachioed Professor Skelton into carrying out on attack on Atom, and they also proceed with their plans to gas the mayor at midnight.
Some great old school model effects near the end of this episode, I particularly enjoy that stop motion animation where the ZZZ Gang's car sprouts wings.
I've made a few minor tweaks to the first two episodes. The only major change is that the name of the town where peace talks are taking place should be Romanized as Hakone, not Hakoneshi. https://en.wikipedia.org/wiki/Hakone Sounds like a very nice town, I'd love to take a vacation there someday.
