In the Jurassic Park and Jurassic World movies, it's safe to say the thing visitors have had to worry most about -- well, apart from mankind's desire to play God and experiment -- has been the dinosaurs. We've seen them running loose on Isla Nublar, Isla Sorna and in the American open, hunting and doing what apex predators do best: feed. However, as the Season 4 trailer for Jurassic World: Camp Cretaceous reveals, while the kids did have to contend with dinos before, the newest monsters they'll have to face aren't even reptilian beasts.

The video clocks in at just over a minute, and at its breakneck pace it does well to tease what's to come without giving too much away. The kids ended last season on a boat, leaving Site A, but now, we see a Mosasaurus shipwrecking them on an island that showrunner Scott Kreamer confirms isn't Site B -- it's a totally new island.

Robot dinosaurs appear in Season 4 of Jurassic World: Camp Cretaceous

And as they explore it, it's definitely a death trap, first starting with the kids realizing it's filled with artificial environments. We see a desert setting, as well as a snowy one, with doors opening to take them into control rooms, making it seem like this is a park from HBO's Westworld.

It's epic trickery, frightening Darius and Co. because knowing the landscape on Isla Nublar put them on level pegging with their hunters. Now, if they can't judge the terrain, they'll be easier prey. In addition, the drones spotted in previous seasons spying in on them are once more present, corralling a wounded T-Rex. It suggests some operator could use it for the opposite mission -- sending dinos after the kids, which lends credence to a puppet master existing, adding a sinister layer of complexity to the mix.

It's not known if this is linked to Ingen remnants, breakaways from the Masrani Corporation that bought John Hammond's company, or a totally new company -- the latter being an idea this series has introduced via its corporate espionage arc in Season 1.

To make it worse, we see a dino-robot coming after the kids, which shoots energy beams from its mouth. It amps up the danger factor as bots that aren't flesh and blood won't get scared due to their programming, would be able to hunt in the night and won't get tired. It's the ultimate killer, but just when you think that can't be topped, Darius' team encounters a saber-tooth tiger in one of the show's biggest bombshells.

It leaves fans wondering what other prehistoric creatures are alive here, which is something the teens wouldn't have trained for. It's quite sadistic but promises an action-filled, emotional rollercoaster to come as the kids are now facing, undeniably, their most unpredictable enemy to date, with the island taking on a devilish life like never before.

Jurassic World: Camp Cretaceous Season 4 premieres Dec. 3 on Netflix.
