Amber Mosquito

Using this item will cause a baby dinosaur to spawn and follow you. Using the item does not consume it, and it will remain in your inventory while the dinosaur is active.

If you jump too high into the air, a pterodactyl will carry your dinosaur by the tail. The baby dinosaur is immune to damage from enemies and despawns upon player death.

This item can be found by putting Silt into a Extractinator, with a 1 in 5000 chance.

Trivia

 * This item is a reference to the film Jurassic Park, where dinosaurs are cloned using blood found in mosquitoes trapped in amber.
