The Microbe

To me, the end is too barren. That's why I created this mob suggestion.

Appearance - 
A Microbe would be a new mob that spawns in the end rarely. But more on that will be later. They are very similar to the common Bacteriophage. They would be close to the size of a player, just a bit smaller. Six pure black legs would be on the bottom. There is a center tower-like area, which connects to the legs and top. On the bottom of this tower is a sort of mouth, the reason it can damage the player. The top is very similar to the Capsid Head. It has a special design, but it has no eyes. The Head is purple, and can puff up for certain reasons, which will be said below.

Behavior - 
As recently wrote, the Microbes are blind. They depend on their legs to feel like feelers of an insect, and depend on sound to hear dangers nearby. If a Microbe feels a Chorus Tree, it will climb up similar to a spider and begin to eat any Chorus Fruit available. They have a special behavior. Microbes can puff the Capsid Head up to above the player's size. After this, it can do 3 long jumps, where it takes no fall damage after and falls slowly. During this, it can either attack the player if it was detected, climb up Chorus Trees, or just float around. Microbes can detect players within a certain block radius. If the player is sneaking to stop any noise, it can't detect the player unless touched or attacked. Upon detection or attack, it will puff the Capsid Head up to be above the player's size.
