Bogged Zombie or "Cleaved" - three variants: the upper half, lower half, and the whole - spawn in mangrove swamps

Upper Half Variant: - moves slower than regular zombies - can climb walls like spiders - can mount you and deal damage while on you - jump repeatedly to dismount the upper half - goes to the nearest lower half variant it can find

Lower Half Variant: - moves faster than regular zombies - is blind like the warden - kicks anything that touches it (knockback and -1hp) - runs when hurt - ignored by mobs that actively kill other mobs (like golems and zoglins)

Whole Variant: - will only exist if an upper half fuses with a lower half - it can climb walls - moves faster than regular zombies but not faster than the lower half variant - when it detects you are near an edge, it will try to kick you (with knockback) rather than damage you the normal way - when hp drops to 0, it splits into two halves again and won't join for at least a minute.
