Attention: If anyone knows advanced strategies for specific tier 10s, please let me know! I am making a separate guide for more advanced players! :D
Default speed: 100
HP: 450
Damage: 80
Armor penetration: 50%

Cookiecutter sharks can live in the deeeep.
Abilities:
Boosting will make the cookiecutter shark lunge forward and deal 100 damage, using a boost bar.
Keeping the boost charged will make the cookiecutter shark more and more invisible.
Releasing the boost will make the cookiecutter shark become fully visible and lunge forward.
Hitting an animal at tier 5 or below will make the cookiecutter shark grab the animal. Shaking the animal vigorously will deal up to 35% of the animal's maximum HP and give the cookiecutter shark up to 700 XP.
Hitting an animal at tier 9 or 10 will make the cookiecutter shark latch onto them for 3 seconds. This deals 100 damage instantly and an additional 40 damage each second. When the cookiecutter shark detaches from the animal, the animal will be given the bleed debuff for 4 seconds. The cookiecutter shark will get 5000 XP and +30% speed when detaching.
The cookiecutter shark will not gain XP if it has enough XP to evolve.
Cookiecutter sharks cannot damage or be damaged by cookiecutter sharks.
Strategies: Keep your boost charged at all times, as this will make it harder for other animals to see you. To make this effect stronger, swim around food to make it seem like you're not there. Use your ability on big tier 9 and 10 animals to increase the chances of latching on.
