Gordon and Susan join Big Bird for a whimsical pretend tea party, but Big Bird's imaginary friend, Mr. Snuffleupagus, remains unseen. Gordon later attempts to grade papers in peace at Hooper's Store, where Mr. Hooper's well-meaning interruptions keep him from his tasks. Meanwhile, Telly learns about the concept of "between," and Oscar leads a musical rally for Grouch rights in Central Park. Big Bird and Snuffy have a brief fallout but quickly reconcile, realizing that friends can differ in opinions. Susan works on her car and ends up pleasantly surprising Oscar with some spirited banter. The episode concludes with Oscar playfully admiring a greasy car part Susan gifts him. Alongside these scenes, various cartoons, songs, and Muppet sketches explore the letter V, counting, and imagination, creating a delightful mix of education and entertainment on Sesame Street.
