"The Missing Invitation" is the 28th episode of Little Einsteins, and the last episode of Season 1.
The team, with their friend Butterfly, see that the other butterflies have an invitation to a migration party in Angangueo, Mexico. But then, their friend becomes sad because he did not get his invitation and three other butterflies are teasing him. The mail carrier butterfly says that the missing invitation is in a mailbox, but in the wrong place. So the team must go to four places to find his invitation on a mailbox: Niagara Falls, the United Nations headquarters in New York City, Big Cave in Utah, and the field of cows in Texas.
