Crassigyrhinus Scotticus, also known as the Scottish Swamp Monster, was a large amphibian that attacked creatures that got too close to the waterline. It spawns as a hostile mob in the Carboniferous Dimensions Coal Swamps.

Crassigyrhinus Scotticus will simply attack any mob that touches the water, it may also tug them further underwater to attempt to drown them. The murky water it hunts in makes it a very dangerous creature as it is difficult to spot. It drops Amphibian skin(80%) and Streamlined tail(20%). It has 6 hearts, so a swing of a Diamond Sword will kill it.
