Dr. Jacob

Dr. Jacob is the head researcher of the Dinosite mutagen at the Kimra Xenobiological Laboratory, and a mini-boss in Blue Stinger.

When you reach him, he'll have already undergone Dinosite mutation, evident by his additional appendages. After you approach him, he undergoes an additional mutation, growing into a bigger monster, and his skin turns blue.

Upon defeating him, you receive Jacob's Safe Key, which opens a safe directly behind him, containing Jacob's Disc and Dr. Jacob's Key. The disc can be used on the computer next to the safe and the lab up on the main floor to access additional information about the Dinosite mutagen, while the key is used to access a locked door that grants you passage to the third floor basement of the lab, the new drug storage room (A-Vect serum room), and the Aquatic Life Experimentation room.
