This is Gagaga Gago's story as written on its tag:
"Gagaga Gago is a loner. During the day, he strolls through the suburbs of BeastsTown and at night you can see him in the backyards of the restaurants downtown. One doesn‘t know exactly what he’s looking for, but he’s always looking for something. Probably – rumor has it – for the meaning of life. Who knows whether he‘s found it yet."
