The Lamprey, unlike most animals, is long in length- but still a rectangle. It has two small oval eyes dotted on one side of the head and has a mouth lined with two layers of jaws. It has two swimming fins just below the eyes, and one big, long tail fin.
For The Lamprey: Edit
Attach yourself to other Animals by boosting and slamming into them. By latching onto them, you get a part of the food that they feed off and evolve quicker.
Against The Lamprey: Edit
Since the Lamprey is quite weak, it's easy to kill- a few hits should do. But in order for it not to attach on you, where you cannot attack it, it must have no boost, so try and outrun it, which will leave it drained of its boost and unable to latch on to other animals.
Or, try and please it- feed on food until it has gathered enough from you to evolve. When it evolves, either to a Jellyfish or a Frog, it won't be able to latch onto you, and should be easy to prey on, and to kill.
- It is the only animal that can latch itself onto other animals, without injecting a poison into them or harming them while doing so
