Dexter and Blossom's Prehistoric Adventures/Tropes

This is the list of tropes for Dexter and Blossom's Prehistoric Adventures. This has also unmarked spoilers for the series.

Tropes
Cooper's Hawk: “It was all just an act?” Mandark's duck: “Sayonara, Mandark!” Alpha Dire Wolf: “Rule number 2 of hunting: Do not hunt prey that can fight back!” Blossom: “Animals, extinct and endangered, must work together.”
 * 3D Effects, 2D Cartoon - They are everywhere. Especially during underwater scenes in Seas of Monsters, The Giant Delta, Monster Whale and Life at Its Origins, since most of the prehistoric sea creatures were rendered in computer-animation.
 * Dexter's own laboratory was rendered mostly in computer-animation, when compared to the original show's 2D design.
 * Action Girl - Ms. Bellum fights off a pride of American lions in Feathered Forest.
 * In the same episode, Ms. Keane fights off Sedusa to save her husband, Professor Utonium.
 * Action Prologue - The entire series starts off with an unnamed Tyrannosaurus fighting an unnamed Triceratops. After all that, the Triceratops wins the fight and the Tyrannosaurus loses, before shifting to present day during Ms. Keane's class field trip at the Townsville Natural History Museum.
 * Actor Allusion - Billy West, one of the voice actors for Bugs Bunny, voices Buddy the eastern cottontail. Buddy also shares the same personality of Bugs.
 * Gilbert Gottfried, the voice of Iago from Aladdin, voices another parrot by the name of Percy.
 * Adaptation Dye-Job - Mandark's duck was yellow in Dexter's Laboratory. In this crossover series, she was colored white as yellow only occur in ducklings.
 * Adaptation Species Change - Dexter's monkey was a generic brown monkey in Dexter's Laboratory. In this crossover series, he is a white-headed capuchin.

 * Anachronism Stew - In Seas of Monsters, Lythronax is seen hunting a herd of Claosaurus. The problem is that Lythronax didn't exist until 80.6 million BC.
 * Sandstorm merges the Djadochta Formation and the Nemegt Formation.

 * Animal Talk - Most of the animals can talk to one another, but not to humans. Expect for Bubbles, who has an ability to talk to them.

 * Animesque - For all the animal characters (Sans Bullet the squirrel).
 * Art Shift - To the movie-quality traditional animation style.

 * Ms. Keane also counts as Professor Utonium's new wife.
 * Princess Morbucks also counts as well.
 * Attention Deficit... Ooh, Shiny! - During In the Beginning, Diana and Dave, along with a pack of Acheroraptor, were seen feeding on a dead Torosaurus. Then, they hear Dee Dee screaming as she gets kidnapped by Mandark. Only Diana and Dave have left the carcass to see what happened. The Acheroraptor pack, however, spot a Cimolestes passing by and chase it.

 * Beware of the Nice Ones - Koroleva may be the kindest leader of her woolly mammoth herd. But if you harm her calf, Koroleva will trample you down.

 * Professor Utonium calls Mel the Gigantopithecus a bigfoot.
 * The Cameo - Mac and Frankie Foster from Foster's Home for Imaginary Friends make a brief non-speaking cameo appearance in Feathered Forest as they hear Bubbles' various animal calls to the animals from the previous episode that rampage Townsville as she annouces the fight duel between Fang and the alpha of the dire wolf pack. They (Mac and Frankie) reappear at the end of Back from Extinction.
 * Big Dog and Little Dog from Two Stupid Dogs also make a brief non-speaking cameo appearance.

 * Darker and Edgier - This crossover series is a lot darker than the original two shows. Which is why the series was rated TV-PG.
 * A Day in the Limelight - Professor Utonium and Ms. Keane are the main focus in Feathered Forest.
 * Dee Dee and Beau are the main focus in Down Under and Finding Dee Dee.
 * Life at its Origins focuses more on Stan the Tyrannosaurus and Diana the Dakotaraptor than the main cast's adventure in the Cambrian seas to find an Anomalocaris.
 * In Lost in Dinosaur Park, Bullet was stayed behind with Percy, Buddy, Opal, Reynard, Valentino and Ginger to guard the Powerpuff Girls' house while the main cast is in the Late Cretaceous Canada. But, when Buddy got kidnapped by Mandark and the Rowdyruff Boys, Bullet and her friends have a rescue mission, with the help of the two spies in their black bodysuits, that are really Professor Utonium and Ms. Keane in disguise.
 * The stars of Super Gatorland are actually Martha and Paul the passenger pigeons, not Deinosuchus.

 * Evil Counterpart - Indominus Rex to Black Beauty.
 * Expy - Buddy is a complete expy of Bugs Bunny.
 * Fake-Out Opening - Bullet's introduction in the first episode. First, Buddy and his rabbit friends were chased by Reynard the fox. Then, Bullet shows up, lures the fox into the tree and Reynard got hit. Suddenly, Bullet sees a Cooper's hawk chasing a flock of house sparrows and Bullet does knifehand strike in the hawk's head. The Cooper's hawk falls down to the ground, a victory for Bullet and then, Percy says “Cut!” and is amazed about Bullet's training. And turns out that Buddy and Reynard are really just Bullet's friends. Lampshaded by the hawk.

 * Halfway Plot Switch - The plot of Super Gatorland is about Dexter and Blossom's team adventures in the Late Cretaceous Texas to encounter a Deinosuchus, and then the rest of the plot is about Dexter and Blossm, along with Bubbles and Bullet, giving Martha and Paul the passenger pigeons a tour of the modern world.
 * Happily Adopted - The Rowdyruff Boys were all adopted by Ms. Sara Bellum at the end of Back from Extinction.
