For those who didn't get Robot Santa an SDCC last year, he can finally be completed with series 6, which includes Cloberella and Amy Wong. With Amy the Planet Express crew is close to being finished and Clobberella finishes off the New Justice Team.
WARNING: Be careful removing Robot Santa's arm holding the tommy gun. The hand broke off from the gun when removing it, but I was able to fix it with some glue.
