Júlio is Frank's Mexican gardener who gave him a set of flowers for his romantic date with Maxmoefoe in the episode VOMIT CAKE, Not much is known about Júlio because he was mentioned only once. It's very plausible that Júlio speaks Gardener. In Frank's older video HOW TO SAY HELLO IN 30 LANGUAGES, the Gardener language is shown. It's also speculated that the gardener has some relation to stealing cars, because, "Hello" in Gardener language is, "Hey ese, I'm breaking into your car!"
