Return to Recap: The Smurfs.
A Smurf dreams to be able to travel to the stars. To that end, he builds a spaceship that operates on pedal power attached to a propeller at the bottom of the ship.
Tropes associated with this story include
- Adaptation Dye-Job: The Papercutz English translation changes the Schlips (renamed the Swoofs) from orange to green.
- Adaptation Name Change: Besides the Schlips being renamed Swoofs, Harmony Smurf was renamed Rocker Smurf in the original English translation of the story.
- Are We There Yet?: During the trip to the volcano, the Smurfs ask "Is it really that much farther, Papa Smurf?" several times. They also do this on the return trip home.
- Big "SHUT UP!": Done by Papa Smurf to his little Smurfs when they ask one Are We There Yet? too many.
- Blame Game: Or rather, the Blame Chain, as when Astro Smurf climbs up what's supposed to be a greased pole effortlessly and Grandpa Swoof finds out that it wasn't greased, one Swoof blames another for not greasing it, and that Swoof blames another, and so on.
- Cannot Keep a Secret: The title character tells one inquisitive Smurf about the spaceship he's intending to build and warns him to keep it a secret. However, that Smurf ends up telling another Smurf, and soon enough the whole village knows about it!
- Casual Interstellar Travel: Failed. Astro Smurf built himself a space rocket but couldn't even get it to take off. The other Smurfs set up an elaborate hoax to convince him he had actually made it to another planet.
- Epic Fail: The Smurfs try to devise some really difficult tests to convince Dreamy to go back home, but most of them fall flat; they tell him to climb a pole, and intend to grease it, but one Smurf puts another Smurf in charge of that, and it doesn't get done. They try to get Dreamy to fight Hefty, but because as Schlips they couldn't be told apart, Vanity was mistakenly chosen. They tell him to swim across a lake carrying a rock, but the rock is pumice, which floats.
- Faceless Masses: Because the Smurfs all looked alike as Schlips, Papa Smurf had a hard time picking out which one was Hefty so he could fight Astro Smurf. He made his best guess, only to find out that the Smurf...er, Schlip that he picked was Vanity!
- Fauxtastic Voyage: The Smurfs disguise as caveman-like creatures named Schlips to allow Astro Smurf to fulfill his dream.
- Flower from the Mountaintop: One of Astro's challenges to become a Schlip is to get an edelweiss flower from the top of a mountain before sundown, and given that this task takes place around sundown, this gives Astro very little time to accomplish it. After being unable to climb up the mountain, Astro sees a stork and uses it to complete the challenge in record time.
- Perma-Stubble/Tribal Face Paint: The off-color rings around the Schlips' mouths could be interpreted as either.
- Oh Wait, This Is My Grocery List: Harmony Smurf (or Drummer Smurf) makes an announcement that Astro Smurf's invention is ready to be unveiled, but the first thing he reads off is a recipe Greedy Smurf had given him.
- Slipping a Mickey: Papa Smurf puts one in the raspberry juice to make Astro Smurf fall asleep for his journey to the world of the Schlips and for the return trip. Of course, the sleeping potion eventually wears off, requiring constant drugging to keep Astro asleep.
- Symbol Swearing: Papa Smurf as Grandpa Swoof in the non-English versions when he finds out that the rock he had Astro Smurf try to swim across the lake carrying was pumice stone.
- We Are Not Going Through That Again: Yelled by the Smurfs at the end of the story when another Smurf suggests how he could make a trip to outer space.
