Season 1 newcomers include:

• Winkler as Boris, Tommy's Zayde, in "The Bubbe and Zayde Show."
• Kurtz as Minka, Tommy's Bubbe, in "The Bubbe and Zayde Show."
• Schwartz as Lord Crater, the pompous but truly evil villain of The Final Eclipse movie franchise, in "Final Eclipse."

In the all-new season one episodes, the babies will continue to find themselves in a variety of situations by using their wild imaginations, including defeating an "outer space villain," traveling through Chuckie's dad's body, embarking upon a daring mission to break Angelica out of preschool and more. The new batch of episodes also includes a half-hour, Halloween-themed special where Tommy needs his friends' help to save Angelica after she turns into a werewolf at a scary Halloween party as their parents seem to disappear one by one.
