I heard Juss's voice as "Swiper the Fox" from Dora the Explorer in that last line.
Juss has been imitating Swiper since he was three. It was really funny when the tiny three year old started going "Oh, Maaan!" Back then, I didn't know it came from Swiper and I was really confused about how my three-year-old had picked this up.
Today, he blamed Arko for turning on the TV. I pointed out that Arko did not have the ability to manifest on this plane of reality. Juss admitted that Arko was not real, adding: "Sometimes, I can barely see him!"
