Arthropod mob Mimic

Mimics are small, hostile blue bugs that spawn around Overworld frequently, like zombies, creepers, etc. They have 16 health like spiders, and although do little damage (2 at normal), have a "surprise attack" that deals massive damage (8 at normal).

Mimics are curious creatures, and wander around looking at other mobs. Upon finding another mob, they look at it for a few moments, and add that mob to their "copy list". If they spot a player, they check their list and select a mob. They select a mob based on their "priority", which takes into account the following (from most important to least):
1. It's a passive creature;
2. It's not a monster creature;
3. It's a neutral creature;
4. It's a silent creature;
5. It's an intimidating creature (includes some stronger mobs like enderman, iron golem, warden, the Wither, etc);

After selecting a mob, the mimic turns into said mob and stalks the player. If they are attacked by the player they instantly turn to a mimic again, else they jump out of cover and do a "surprise attack".

When spawning, mimics already start with a few mobs in their "copy list", with common mobs being more likely than rarer ones (this is how it's sometimes able to copy players!).

Other factors:
- If the mimic spots an agressive mob, it tries to save itself by disguising, for example turning into a creeper to avoid an iron golem, or a zombie to avoid the Wither;
- Mimics can copy players on Creative mode, as they don't attack them;
- Mimics are affected by Bane of Arthropods;
