In 2010, the sequel Tasty Planet: Back for Seconds has come out, in which our protagonist can time travel. It also features multipart levels, which means once you reach a certain size, the game zooms out to reveal a bigger scene, and you find yourself small again with new things to eat.
Then a spin-off is made in the name of Tasty Blue where you play as a fish, a dolphin, and a shark. The gameplay and features are still similar with the second game.

More recently, another game in the series came out, called Tasty Planet Forever. This one consists of multiple parts, each with its own protagonist (including the Goo). The parts are about ten levels each, plus a similar amount of bonus levels.
This game includes examples of:
- Adorable Abomination: The Grey Goo is capable of becoming a Spacetime Eater. And looks like this.
- All the Worlds are a Stage: In Back for Seconds, the last level in each time period is a concatenation of multiple levels from that period, with an added twist ending.
- Anti-Frustration Features: Back for Seconds, as well as the mobile version of the first game, made it so that getting actually eaten is extremely unlikely, and in the latter, any entities that could eat you were changed to simply make you shrink, whereas in the PC version of the first game, some entities that are larger than you can actually eat you and cause the level to fail.
- Apocalypse How: Class 0, then stepping from Class X through X-4. And then subverted when your Blob Monster becomes so powerful that in turns into a new Big Bang. Played straight in the sequel, though.
- Big Eater: The Grey Goo that you play as.
- Blob Monster: The Grey Goo.
- Brain in a Jar: The Professor and assistant become these to survive until the blob appears in the future.
- Captain Ersatz: In Back for Seconds, the Grey Goo eats "Monsterzilla", which causes the present day to be attacked by some suspiciously similar looking monsters, including a giant gorilla, a giant moth, and a dragon with three heads.
- Clown-Car Base: In some Japan levels in the sequel, Ninjas come out of a Cherry Blossom Tree.
- Cute Machines: It's a blob with cutesy eyes!
- Earth-Shattering Kaboom
- Energy Weapon: In the Future series of levels in Back for Seconds, we have these not just on Tanks, but Ants, Rats, and Cats.
- Everything Trying to Kill You: In the ocean and cosmos, almost everything bigger than you will kill you.
- Energy Being: They appear in a few Orbit levels as "Energy Entities".
- Extreme Omnivore: Technically, Ultimate Omnivore.
- Genre Blind: The scientists who created the blob have evidently never heard of the Grey Goo scenario.
- Gone Horribly Right
- Grey Goo
- Made of Explodium: In the sky levels, planes will explode on contact with other planes, hot air balloons, the grey goo, kites, or even birds.
- Marathon Level: The 3 Endurance levels, the last of which requires 1 hour of concentration to beat.
- The last level of Back for Seconds is far longer than any level before it. Gold medal time is 21 minutes 20 seconds!
- Mega-Microbes: That eat galactic superclusters.
- Non-Malicious Monster: The grey goo.
- Non-Standard Game Over: Run out of stuff to eat before the meter is full, and you get a special fail message saying there's nothing left to eat.
- Our Time Travel Is Different: Lampshaded by the scientists.
- Planet Eater
- Protection Mission: In the sequel, you allegedly have one of these in the Roman series of missions, where you're supposed to protect five Ballistas from Roman Gladiators until you can eat them. But really, all you need is to maximize your meter. Even in you fail to protect them, it's still possible (though not easy) to win even in Timed Mode.
- Red Eyes, Take Warning: White blood cells have red eyes to indicate they can hurt the goo when touched (and appear in the level that teaches you about that fact, fittingly enough).
- Reset Button: Back for Seconds starts off with the same scientists inventing the same Grey Goo, but this time it's just something the elderly scientist made out of boredom. Presumably, this is in the new multiverse.
- Sci-Fi Writers Have No Sense of Scale: The goo is supposed to be able to eat anything smaller than itself, but sometimes what it can eat makes little sense. For example, it can eat entire sharks when it's less than a meter in diameter.
- In the second game, the size you can eat something at is determined from what it looks like from the top down. Thus, you can eat humans at 35cm.
- Serial Escalation
- The first game starts with you eating specks of dirt, and ends with you eating the fabric of time itself. Then you explode, becoming a new Big Bang and birthing a new universe.
- The second starts with microbes, and ends again with the fabric of time. Then you find that the universe rests on a Turtle of Time, which rests on an infinite pile of Turtles.
- Forever starts with quarks and ends with multiple universes... that look like quarks. Then you work your way up again.
- Shown Their Work: The Cretaceous levels of Back For Seconds avoid Anachronism Stew flawlessly, not only with dinosaurs but with mammals and insects as well.
- Spared By Adaptation: Tasty Blue has the scientist and his assistant being the only humans to survive the shark's rampaging diet.
- Time Travel: Back for Seconds has the Grey Goo eating a time machine, then going back to the Late Cretaceous, then to Ancient Egypt, Ancient Greece, feudal Japan, and the distant future.
- Timey-Wimey Ball: Lampshaded in the comic that follows the final Egypt level in the sequel.News Broadcast: This just in! The pyramids of Giza have gone missing!Older Scientist: The goo must have eaten the pyramids!Younger Scientist: If he ate them 3,000 years ago, why did they disappear just now?Older Scientist: *shrugs* Time travel's complicated.
- Timed Mission: In the sequel, providing more of a challenge.
- Turtle Island: The final level of Back for Seconds has the Grey Goo devouring all the World Turtles holding up the universe before imploding into a new one.
- Unrealistic Black Hole: In Cosmos 4, black holes actually suck in stars, yet for some reason don't suck in the grey goo. Same applies for the sequel.
- Villain Protagonist: While not exactly evil, the grey goo still eats the Universe.
- Womb Level: During the tutorial levels of the first game, the grey goo bites one of the scientists and spends a level in his bloodstream.
