So the Avenue Q Gang decide to visit the Big Blue House.

When they arrive at the Big Blue House, Bear, along with his friends Ojo, Treelo, Tutter, Pip, Pop, Ursa and Tally greet them by singing the theme song. After that, Bear tries to figure out what's that smell. He sniffs the Avenue Q Gang and tells them that they smell sweet like honey. Then Bear, his friends and the Avenue Q Gang sing the song That's My Name as they introduce themselves. After the song, Princeton tells Bear that he and his friends got the invitation to Tutter's birthday party in the Big Blue House. In the kitchen, they meet Pip, Pop and Tally and tells them that it's Tutter's birthday. Tutter then appears and sings to everyone about what he wants to do when he is older.

Then Bear and the Avenue Q Gang decide to check the mail while Bear sings about what's in the mail. Inside the mail is a letter from Grandma Flutter which reads that she's excited for her son Tutter's birthday and wishes him a happy birthday. Bear then asks the Avenue Q Gang if they would like to help get ready for the party. Everyone then agrees.

Bear and the Avenue Q Gang then find Ojo baking a birthday cake. She asks Bear and the Avenue Q Gang to help her finish baking the cake. They all agree and help Ojo with Tutter's birthday cake. Afterwards, the cake is ready and Ojo decide she to give a taste test. She licks the frosting and says that it tastes yummy and thanks Bear and the Avenue Q Gang for helping her.

Later, Bear and the Avenue Q Gang find Pip, Pop and Tally blowing up balloons for the party. Rod then helps by blowing a balloon, which makes his voice sound high pitched that the balloon pops. Then Pip, Pop and Tally sing the song Otter Love.

All of a sudden, Bear and the Avenue Q Gang heard Shadow laughing. Bear then asks the Avenue Q Gang to sing Shadow's song with him. So they all sing Shadow's song as they look for her. Then Shadow appears and greets Bear and the Avenue Q Gang. Bear then asks Shadow to tell him and the Avenue Q Gang a story. Shadow then says "Just watch!" And the screen then ripples to a shadow puppet segment of a female dog singing Hey, Diddle Diddle at a jazz club. The Avenue Q Gang then say that they loved the story. Shadow then tells Bear and the Avenue Q Gang to try and catch her if they need another story and disappears.

Bear and the Avenue Q Gang then find Treelo and Ursa wrapping a birthday present for Tutter. But Treelo is obsessed with the streamers. So Bear asks Treelo and Ursa what they're giving to Tutter for his birthday, But Ursa says that it's a secret.

Everyone then heads to the living room in time for Tutter's party to start. Ojo made the cake, Treelo and Ursa wrapped the presents and Pip, Pop and Tally blowed up the balloons. But there's still one thing to do... Surprise Tutter! when Pip, Pop and Tally accidently popped a baloon and hears Tutter. Everyone hides and Pip and Pop turn off the lights. Tutter comes in the living room and wonders where everyone is. Bear, Ojo, Treelo, Pip, Pop, Ursa, Tally and the Avenue Q Gang all jump up and say "Surprise!" Tutter is very surprised. But luckily, Bear tells Tutter that the party is for him. Then everyone sings Happy, Happy Birthday to Tutter.
