134 when in the different testing rooms seems to "eat" by absorbing objects and/or animals, although it does not have organs or a brain,it does move on its own,get hungry,and feel emotion,we do not know how,and we used to have multiple,but it appears that they don't "like" each other and the blue one absorbed them all after a long "fight" you could say. Slimen is not hostile(to humans) but it will absorb a human if hungry enough we know it can regenerate but we decided to see how much and shot it,it can regenerate very fast. Danger Class:Safe (Note:Slimen seems to move around and absorb more things when around 186,trying to impress it)
