Terrible Beholder

Terrible beholder is a very dangerous hostile creature that spawn in all worlds through monsters portals in multiplayer games and that spits fireballs.

Terrible
It is very similar to the regular beholder. The differences are the following:
 * the appearance;
 * it has 33% more health;
 * it has an extra attack: the fireball; and
 * its melee attack is weaker in damage and has a hit rate 25% faster.

Mobility
Despite its description, the terrible beholder cannot fly. It floats depending on background and foreground walls (much like giant ants and hens).

It can fall from a ten block height without being hurt.
