VHS Extended Version
The viewers are greeted by three young children who are getting ready to watch Blue's Clues. Steve is on the television trying to make up a birthday dance for Blue but he had a little trouble. Steve tries a birthday dance on the children watching him on TV. Steve was not doing so good. Then, he heard Blue who is still sleeping. Blue was going to wake up soon and today was her big birthday party and so much has to be done. Gifts have to be wrapped, streamers have to be strung, balloons have to be hung, party hats to make, birthday food has to be made and lots of Blue's friends are coming over. And Steve still has to make up a birthday dance for Blue. Steve asks the children, "Do you know a birthday dance?" and the children respond to him "the birthday candle dance". The children said that they will teach Steve how to do it but he has to skidoo to see them. Steve skidoos and is so glad the children invited him over so that he could learn the birthday candle dance. The only downside is, he does not have a lot of time and Blue's party is today. Steve talks to Timely and asks him how much time he has before Blue's birthday party because he still has to learn the birthday candle dance. One of the three kids tells Steve that the clock does not talk. Steve can prove it to them. The kids wanted to see for themselves. Steve and the kids watch and wait. In a few seconds, eyes appeared. The kids gasp and then a mouth appears. The kids laughed. Timely greets the kids and Steve. "Steve! Blue's birthday party starts soon. You need to be back when both my hands are on the number 12. That means 12 o'clock. You don't have much time" says Timely. Steve only has ten minutes to learn the birthday candle dance. Steve sits down on the floor as he watches the kids how the birthday candle dance goes. Steve watched them do it with and without the music. Then, Steve had to try it. Steve remembers the words but he had to learn the right movements. He had to put one foot out, bring it in, put the opposite foot out and bring it in. Then he had to jump and point at the same time. Next, he had to take three steps forward while bringing his arms out. The next move is to stick out the thumbs. The next move is to step back three times and roll the hands. Then, he had to do the twist to the left side, the right side and then twist to left. But Steve also had to go down while he is twisting. So, all he had to do was just bend his knees. The last move is that Steve had to stand up straight and tall and bring his hands up over his head to make a candle. The last part is that Steve has to imagine himself being blown out just like a real candle. So, he just has to touch ground with his hands. When Steve finally got the right movements, he joined the kids in the dance and they succeeded. Timely tells Steve "It's almost time for Blue's birthday party. It's time to skidoo!" Steve saw that it was almost 12:00. Steve had to skidoo back to the TV. Steve says goodbye to Timely and Timely tells him, "Have a great 'time'" and giggles. As Steve skidoos back into the tv, the episode starts.
After Blue blows out the candles, Blue leaves the table and is nowhere to be found, so Steve heads inside the house to try to find her. He thinks he has found her behind Sidetable as he sees the party hat she was wearing. But it turns out to be apart of the decoration, and this huge "thinking chair swirled red" present appears, and it is for Steve. Steve denies that it is for him since it is not his birthday, but the children persuade him to open the present to find a large "bedroom polka doted purple" present, which turns out to be a medium "kitchen swirled yellow" present, which then turns out to be a small "Steve striped green" present. Inside, it is a heart shape cookie that says "Thank You" on it. Blue had made it for Steve as a way of saying thanks for the party. They get back outside to the party and ends with the so long song and credits on the banner.
