This episodes starts with Joe (in his Orange Shirt) saying hi to the viewers, and he said that they needed help today because there is making an alphabet train. First there is the letter a and airplane starts with a. Next, there is b and Blue comes to the letter b. Then there is c, d and e. A crayon starts with c, a drum starts with d, and an eagle starts with the letter e

Then, we came to Sidetable Drawer for the notebook, and she has something for the letter f, a fox. After Blue's Clues was explained, we start looking for clues. Then, there is a clue on that white.

Then we go to Pail for the g, h and i. The options where globe, pumpkin, ice cream, hat, or mittens. Respectively, g, h and i are globe, hat, and ice cream. We then here Pail said Joe was for the j.

Then, Periwinkle then had a leaf for the l, a kite for the k, and mittens for m (just like when we seen mittens before). Joe sang the song to see, it goes "A B C D E F G H I J L K M" but it is wrong. K and L would trade places to be right.

Then, Tickety Tock had something for n, newspaper. Then Joe found another clue on black. After the 2nd clue review, it was Mailtime. And Mailbox founded something that starts with o, an oval. Then Joe got a letter

After that, something that starts with p was founded, Periwinkle and Pail.

Then Slippery Soap asked questions for q and r. Then there was a q for queen, and r for rainbow. Then the there was the s for Slippery Soup, and t for Tickety Tock. Periwinkle brought a ukulele for the u.

Then we see Joe and Blue skiooing to the Magnet Board, and then they were finding something for v, w and x. Volcano came for V, wagon was for w, and x-ray was for x. Then they see a y. It made a yo-yo. Then there was a clue on the Z. Then after he wrote it down, it was time for the thinking chair, but Pail called Joe to put the yo-yo down. Joe then sit for the thinking chair review. The answer was a zebra.

Then, the train was finished and then Joe sang I'll Never Forget My Alphabet, after the song, the episode came to a close.
