Despite the picture being silly, this is a mob idea i came up with.
The Hulk is a very rare mob that can be found deep in dark caverns. This creature is unique compared to the other mobs because this mob can sense you behind walls. If it can't find a path to you, it will then charge into the walls and break them. When it sees you, it will roar at you, and then charge at you. Since it's so heavy and large, it takes time (about 3 seconds) for it to reach full speed. At full speed, it runs double the player's speed and has difficulty turning at these high speeds. This Mob would have 20 hearts and will deal 3-5 hearts per punch. Having a mob that can deform terrain would make this game more challenging and scary.
When charging, weaker materials like dirt will be plowed through while stronger materials like stone will take longer to break.
When this creature dies, you will be given rare items like Diamond, gold or maybe it's armor (Iron armor).
It has a 2x2 collision.
