The Blarg were about 7 000 000 000 In the galaxy because they were all more than friends. So they had lots of rubbish on their planet, so Drek created another planet for them. In reality, The Blarg is a martian landfill used to dump crap that the lombaxes don't want anymore. Ratchet participates on the litering and screws up the environment and treehugger shit like that that fuckers really shouldn't swallow if you know what I mean.
