These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Fossil Fighters
Cargo Ship: McJunker loves mine carts a little too much.
Damsel Scrappy / The Load: Rosie. So very badly. This is even lampshaded when she points out how many times you've had to pull her ass out of the fire.
Ensemble Darkhorse: Judging from the fandom alone, you would think the series is about a group of reptilian aliens and their struggles, and not dinosaur battling. It's probably fair to say some of the fans are just there for the dinaurians.
Fridge Logic After you beat the game, the game makes you shell out $20,000 for an oasis seed, because there's an area called parchment desert where your radar won't work because of how hot it is. Soooooo... how come your radar worked just fine in Mt. Lavaflow?
Game Breaker: Compso. It can lower the opposing AZ dino's attack and defense by 90% AND it gives you a nice FP bonus thanks to FP Plus just by being in your SZ. And you can get one pretty early on.
Raja in Champions, which can be found in the first area, as it can evolve into Giga Raja with a Gold Fossil, which can also be uncovered early with a little dedication. By combining its new, highly-powered attacks with its ability to Charge power, Giga Raja can deal more damage than the highest possible Hit Points of any Vivosaur!
Les Yay: With Pauleen if you play as the female character, as she does get embarrassed when she takes you by the hands
Memetic Mutation: In addition to a guard who talks about miserable little piles of secrets, one kid gets in a "Do Not Want!" during the invasion of the town.
Most Wonderful Sound: The little jingle that plays when you crack open an obstacle and find some money.
