The newest sneak peek for Illumination Studios’ “Minions” answers some burning questions about the pint-sized yellow helpers from the "Despicable Me" films. For example, where they got the idea to all dress in those smart blue overalls? And what they like to eat? (Spoiler Alert: they love bananas).

According to the first full-length trailer for the animated spinoff, which was released by the studio in November, it focuses on the origins of the Minions. After they run out of evil masters to serve, three of the Minions seek out a new diabolical mastermind to lead their gibberish-speaking species. The explorers find their way to 1960s New York City where they struggle to adapt to the world of human beings.

The Minion characters were first introduced in “Despicable Me” in 2010. Their for-the-kids antics quickly stole the hearts of both children and adults, and helped, in no small part, launch the even more successful sequel, "Despicable Me 2," in 2013.

Now, the film’s creators have abandoned making the Minions a part of someone else’s story and are exploring their origins in a standalone film. If the new sneak peak is any indication, it will be full of everything fans have come to expect and love from the characters.

As the new sneak peek indicates, “Minions” will feature voice acting from such stars as Sandra Bullock, Jon Hamm, Michael Keaton, Allison Janney, Steve Coogan, and possibly, Gru himself, Steve Carell. It’s unclear what roles these celebrities will play given that the Minions only vocalize their thoughts with a combiation of giggling and pure gibberish. No other details about the plot of the film after the explorers hit Manhattan have been released.

"Minions" is scheduled to hit theaters in the summer of 2015. In the meantime, fans can watch the trailer, the sneak preview below or sing along to the Minion’s Christmas promo
