4 giant Bugs in Save the Dinosaurs

There were 4 giant Bugs in the Time Period in Save the Dinosaurs in 3D Dinosaur Adventure like Fleas, Scorpions, Pill Bugs and even Mosquitoes. I think Pill Bugs were harmless insect and Fleas, Scorpions, and Mosquitoes were harmful Insects. Fleas can bite and suck Blood, Scorpions can sting with poisonous Stingers on their Tails and Mosquitoes can suck Blood. If any Players go through giant Bugs, they go slowly with those buzzing Sounds.
