The Frog Family goes to the Letter Factory to work on their presentation of letters and their sounds. Mom writes a song about the letters while Dad tours Mr. Websley around the factory. Shortly after Mr. Websley barges in, Dad reminds Leap and Lily to keep an eye on Tad as a favor for him.While Dad was gone, Leap finds some old letters. Tad is sad and he thinks he's too small to learn the alphabet. Tad sadly runs off to learn about phonics.
A professor named Professor Quigley checks with his ruler thinking he's just perfect for learning letters, convinces Tad to allow him to introduce Tad his card, and hands the little frog his talking license so that he can meet the professor. He takes Tad to the A room where the A's say their sound when scared by Quigley dressed as a purple monster. The next room is the B room where the B's sing their sound to Beethoven's Fifth Symphony. Even the Beethoven bust sings too. Professor then yells at the Bs to stop and reminds them that they are not cannons and they are the letter Bs. One of the B letters blows on a tuba with a very strong wind which makes Tad and Quigley fly to the C room where it's very c-c-c-cold in here. Then a snowball rolls them to the D room where the D's play bongos.
In the auditorium, Leap directs the first four letters, A, B, C, and D. Then he turns on his remote control stoplight, causing the letters A, B, C and D to bump into each other and damage the set.
Quigley asks Tad to ask if this is the E room. There is an elephant on the chalkboard in the E room. When Tad asks, an elderly evergreen colored E trainer with a long nose called a trunk, big floppy ears, and beard answers with an "e?" Professor Quigley accidentally breaks the egg when trying to clap. Professor Quigley looks at the egg yolk on his hands sadly manages to clean up the mess on his hands with a napkin. The F room is where the F letters flap their wings and fly as they say their sound. The G room is where the strong G letters are lifting weights. Professor Quigley tries to lift a 2000 pound barbell while he says, "This thing weighs a ton!". In the H room, the H's are hot and water makes them happy. The H room looks a lot like Hawaii!
In the tour, Dad shows Websley where he double-checks each letter to make sure to looks and sounds absolutely perfect. He shows him the first 7 letters on the machine followed by a Burfder, which Dad thinks this is why he double-checks each letter. He removes the Burfder and calls an H at checkpoint 3.
Here comes the next letter, which is I, but on the door a dot above the lowercase i is missing. Quigley tries to fix it with a pen, but it's empty. When he taps it, he face is inked and the dot is above the lowercase i. Inside the I room, the I letters say their sound when the playground slime guns shoot green slime on them. In the J room, the J's jump on trampolines. In the K room, the letter K's do karate kicks, leaving a K-shaped hole in the wall. In the L room, the lime colored L's say their sound to Johann Strauss's Blue Danube Waltz while l-l-licking l-l-lollipops.
In the auditorium, Lily directs this time on the letters I with the ferment piroette, J with a jump split, K with a kick-turn, and L a ledge.
Tad and Quigley next come to the tastiest room in the factory where the M's rub their tummies, eat muffins, and say their sound. Tad accidentally burps and says "Excuse me!" Later on, Professor Quigley knocks on the N letters' door and yells "Hello! Anybody home!" Unfortunately, the crabby N letters won't let any visitors coming in, so they boarded the door. Then, later on they try to go to the N room but the crabby N's still won't let them enter the room, neither at noon, near 9:00, nor next November so Tad and Professor Quigley get yelled at and get kicked out of their room three times and never return to the N room while the mosquito hits itself on the boarded door. Ns still don't want anybody in their room, much to the professor's horror. By the last door slam, Professor Quigley feels sorry for Tad how much they didn't want to stop bothering the grouchy evil N letters, apologizes to Tad for taking him to the N room and tells Tad that they will perhaps have to come back to this room and try again later as the bad news however just as Professor Quigley was about to take Tad away from the N's door, until Tad hasn't been discouraged by coming up with a foolproof idea. He wants to tell Professor Quigley something to make him feel better. That's correct! Professor Quigley has stopped being sad much to tad's hypothesis. The N letters then reluctantly let them into their room. In the O room which is both the big jungle and a big pond, the orchid colored O's say their sound as they swing on vines and yell like Tarzan imitating as they swing over the octopus in the tropical jungle tub. In the P room, the P's turn into popcorn as they say their sound.
In the auditorium, Mom practices on piano as the letters M, N, O, and P sing.
In the Q room, two guest speakers Dicky Duck and Molly Mallard have a quacking debate. In the R room, there is a race track where the red colored R letters ride on. In the S room, an African rock python snake forming the shape on an S hisses to the S sound. In the T room, Tad and Quigley drink tea and watch the turquoise colored T letters tap-dance to their sound.
Smoke called smog fills the auditorium. Lily directs on the letters Q, R, S, and T. But Leap and Lily have just remembered what their Dad said earlier: they need to keep an eye on Tad!
The U room features the U's floating up with umbrellas, the V room features the violet colored V's vibrating to their sound, the W room features the W's rapping to their sound, the X room has an X-ray machine where the Xs get their bones seen, and for the Y room, the Y's cheer to their sound.
Leap and Lily have searched through the 25 letter rooms from A through Y and they haven't found Tad yet, and Dad is almost done with the tour. They'd better find Tad very fast before their dad will get mad at them and throw a big temper tantrum as their punishment.
Finally, Leap and Lily find Tad in the Z room where he's snoring with the Z letters, whom they snore to their sound. Lily wakes him up and tells him he has a problem: Leap's lost his voice. Tad knows how to do it. Dad's tour finally ends.
Dad is concerned about Leap and Lilly. In the auditorium, the letters A to Z appear on the stage and their sounds and sing the letter song.Their dad is very happy. Quigley rewards the Frog Kids for learning the letters not T-shirts, but Alpha-Z-Shirts. The Frog Kids thank Professor with a big cheer. Leap thanks Tad for the special presentation.
The scene then irises out and the credits roll.
