Great Hopper

Behaviour and Tactics
Hops continuously up and down, dealing contact damage. Unlike normal Hoppers, it will change direction to chase the player.

When standing in one place and moving slightly to the sides to avoid its jumps, it is possible to hit it after every landing without taking damage.
