Hello, can the Aternos team please consider adding in the Mod, "Bad Mobs".
This mod lets you edit a config file to make it so that certain mobs that you choose, will not spawn. Helpful for if you dont want any pesky creepers blowing up your house all the time, ect, ect. This includes mobs from mods such as Mo Creatures as well.
