R2D2 didn't do all that bad in the swamps of Dagobah. Unlike our cellphones, Star Wars droids can handle a little water. C-3PO straight up takes baths! So with that in mind, is it too hard to imagine that R2D2 had a torrid love affair with a fire hydrant and what you see below is his offspring? Yeah, still pretty far fetched I guess.
Don't try this at home. Painting fire hydrants is very dangerous and even more illegal. Just wait around for those R2D2 mailboxes to come back around, like they did for the 30th anniversary of Star Wars... that is, if mailboxes still exist in 30 more years.
