Tyrone was in his backyard, looking through a telescope.

"Hmm…" he thought to himself. "No aliens…no aliens…comet…no aliens…"

"Oh, hi!" he said. "My name is Alien Watcher Tyrone. Every night, when almost everyone is asleep, I look up into the sky, hoping to see an alien. It would be great to meet an alien to befriend!"

Then Tyrone started to sing a song about what an alien watcher did.

As soon as he finished his song, Tyrone said with excitement, "Tonight could be the night when I discover an alien!" He ran into the backyard. As he ran, the backyard turned into a large, open field with a huge telescope, and day became night.

Tyrone, now wearing a lab coat, looked through the enormous telescope. "No aliens…no aliens…still no aliens…wait…what is that?" A light that was a colour Tyrone had never seen before shone down onto the field. It shone brighter and brighter, until finally, Tyrone could clearly see a tiny flying saucer that was being driven by a miniscule alien.

The flying saucer flew up, down, and all around. Wherever the saucer went, a line of light followed.

"Say," gasped Tyrone, "this is amazing!"

"I can do more than this," said the alien. Then, through song, the alien explained what he could do with his line of light.

"Can you make words?" asked Tyrone.

"I never thought of that!" said the alien. Tyrone watched, mesmerized, as the alien made words like GREEN ALIEN and ORANGE MOOSE.

"Wow!" exclaimed Tyrone. "The whole world should know about the Amazing Writing Alien!" But when he looked up again, the alien was gone. "I've got to find him!" he decided. He jumped into a van and drove off in pursuit of the alien.

Meanwhile, a strange pink female creature was driving down a street, on her way to a movie. When she was approaching an intersection, she suddenly saw a strange light writing the words TURN RIGHT.

On the other side of the intersection, a purple kangaroo, also on his way to the same movie, saw a mysterious light writing the words TURN LEFT.

So the pink creature turned right at exactly the same time that the kangaroo turned left, and CRASH!

The two of them crawled out of the wreckage.

The pink creature pointed at the kangaroo. "Austin, you almost killed me!" she shouted.

"It wasn't my fault, Uniqua!" replied Austin the kangaroo. "A strange light wrote TURN LEFT!"

"That's funny," responded Uniqua. "I saw a strange light writing TURN RIGHT."

The two of them looked and saw the stream of light zooming off in the direction of the theater. "Maybe someone is playing tricks on us," suggested Austin.

Uniqua and Austin set off on foot towards the theater. As they walked, they sang a song discussing the mysterious light.

Halfway through the song, Tyrone arrived at the intersection, where he saw the two wrecked cars. "That alien must have had something to do with it," he thought to himself. Then he saw the light travelling towards the theater. "I must follow it," he said.

Finally, Uniqua and Austin arrived at the theater. There they saw words above the theater: ARRIVE AT YOUR MOVIE WITHIN FIVE MINUTES AND IT'S FREE!

"Is that light playing another trick?" wondered Austin.

"If we wonder too long," said Uniqua, grabbing Austin by the arm and running into the theater, "we might miss our free movie! Come on!"

As soon as Uniqua and Austin had entered the theater, Tyrone arrived in his van just in time to see the chuckling alien slip through the doors. "I've got to stop him before he plays any more tricks," he said. He jumped out of his van and walked, determined, into the theater.

As Uniqua was dragging Austin through the theater, they passed by something that made them forget about the free movie. A yellow hippopotamus was running a stand that said TASHA'S HOT DOGS, with a strangely-coloured line scratching out the word HOT and the word COLD written above.

Tyrone watched as Uniqua and Austin talked to Tasha, the hot dog saleshippo. "Say, Tasha," asked Uniqua, "don't you usually sell hot dogs and not cold dogs?"

Tasha looked up and saw the flying saucer that had just written the word. "Hey!" she shouted. "My hot dogs are hot, not cold!" Tyrone watched in horror as Tasha caught the amazing writing alien in a butterfly net, cracked open the flying saucer, dumped the alien into a jar, and closed it tight. Then she ran out of the theater with the saucer and the jar.

Tyrone ran to Uniqua and Austin and told them about his discovery. "There is no free movie!" he shouted. "That was just a stupid trick! But we still have to rescue the Amazing Writing Alien!"

The three of them piled into Tyrone's van. Tyrone saw a pickup truck drive off with a jar and a flying saucer in the back. He drove off after the truck, and the three sang a song about rescuing the alien.

Meanwhile, imprisoned in the jar, the alien was very sad. "I should never have played such awful tricks," he moped.

Just then, Tasha's truck came to a halt. It was out of gas! Tasha jumped out of the truck. "I must get gas for my truck," she said, and walked away, unaware that her truck had stopped right on a railroad track.

Tyrone's van stopped behind Tasha's truck. Tyrone, Uniqua, and Austin jumped out. Uniqua opened the jar, Tyrone opened the flying saucer, and Austin put the alien back into the saucer. The alien thanked his three new friends, and promised never to play a mean trick again.

Just then, a rumbling noise was heard. A train was moving towards Tasha's truck!

"Quick, alien!" shouted Tyrone. "Write! Tell the train to stop! If the train doesn't stop, the truck will be totaled!"

Train engineer Pablo had the surprise of his life when he saw very large words in very strangely-coloured light: STOP! STOP! STOP! STOP! STOP!

Pablo applied his brake, and Tasha, with a tank of gas, came back just in time to see the train screech to a halt and just barely avoid hitting her truck.

Pablo jumped out of his train. Then he and Tasha congratulated Tyrone, Uniqua, Austin, and the alien. "Your alien saved our vehicles!" they said.

"This was even better than a free movie!" exclaimed Uniqua.

Then, as the sun rose, with a promise to visit his five new friends again sometime, the amazing writing alien zoomed back into outer space.

Just then, a loud growl was heard. "Did another alien cause another car crash?" asked Tyrone.

"No," said Tasha. "I got hungry on my way to get gas."

"Come to my house," said Pablo. "We have hot dogs."

"And hopefully not cold dogs," joked Austin. The five friends laughed and ran down the railroad track. As they ran, the track, the truck, and the train dissolved, and houses and fences appeared in their place.

Back in their regular clothes, the five friends stopped in front of Pablo's house. "That was an excellent alien-chasing adventure," said Tyrone. "Don't you think?" The others all agreed. Then they all sang:

"We've got the whole wide world in our yard to explore. Now it's time for us to have a snack. Meet you next time, when we're back with your friends, the Backyardigans!"

Then they all entered Pablo's house and closed the door behind them. Tyrone opened the door and said, "Find that alien!" Then he closed the door again.
